criminals caught on surveillance cameras bursting into restaurants, armed with guns and knives. >> at one point i just thought my life was just over. jumping over convenience store counters. >> get on the floor, get on the floor. and terrifying unsuspecting customers and clerks. >> i'm going to cut your throat. >> they had one goal to get what they needed at any cost. but in some cases, when the target is armed -- the tables

are turned. >> he was squirming around on the floor and i said, hey, you weren't thinking about 911 when you was robbing me. >> this is the real deal. this is an automatic. do not like automatics, and now i've got to kill these guys. "caught on camera: armed and dangerous." panic erupts when three masked gunmen storm a restaurant demanding cash and jewelry and it's all caught on surveillance cameras. >> we feel at one point that i was going to die. >> all he has to do is pull that trigger and we're shot in the face. >> more helpless than anything. >> april 23rd, 2011, houston, texas. it's just after 2:00 a.m. and hungry partiers move from the

nightclubs to the 24-hour waffle house to wind down the night. >> one of the party goers' favorite places to eat when the bars close. so we usually get pretty full. >> you could tell that everybody that was at waffle house that night had come from a club. that's what people usually do. >> patrons have just arrived for a late-night snack when suddenly, three men burst in with guns. surveillance cameras record the violent ordeal as it unfolds. >> we hadn't been there not even five minutes because we hadn't even placed our order for drinks yet. saw the guy run in and that's when i noticed he was standing in front of the other guy with a gun in front of his head. >> waffle house employee, brent, is also stunned by the brazen robbery. >> when the robbers came in, my back was towards the entrance. i was making waffles at the time. i really didn't hear them and i turned to my right and saw a lady fall out of her chair. i thought she had just had too

much to drink. that's when i realized what was going on. i saw three guys with guns and i didn't know what to do. try to run, try to -- i just didn't have any earthly idea what to do. >> everybody was like paranoid. you could see everybody trying to hide underneath the table. i was trying to slide down off of my seat to get underneath the table. i couldn't go no where. all i could think about was this guy holding a big gun. the whole time i thought we all was going to die. >> while almost everyone tries to take cover, the cameras cover gerald cole, a regular at the waffle house, making a bold move and attempting to escape. >> once he started i thought i had a chance to break and run to the door. and i looked there was two guys with masks, one hot a shad gun, one had a gun and i broke and run towards the door and there was another guy with a mask on told me that, if you move i'll blow your brains out.

i thought i was going to die. >> instead, the gunman strikes gerald cole on the head, knocking him to the floor. >> he hits me on the right side of my face. at one point, i just thought that my life that was just over. >> i personally thought that they were going to rough him up because he was trying to get out. >> terrified, cole stays face down on the ground while the gunman continues to rob the other customers. >> my friends that were sitting in front of me, she had hid a purse behind her back and he saw that and came and snatched her purse and put it on the table and told her, empty out this purse. i'm guessing she was still in shock, because she was moving in slow motion, just taking it out, one by one, piece by piece. >> they wanted money. wallets, jewelry. he came up behind me and patted me on my wallet that was in the pocket of my pants. he is like, give me your wallet.

i said, buddy, let me give you all the cash i got but let me keep my wallet for my i.d. and my social security card. >> he was like yeah, sure, keep that stuff, it's hard to get back. >> they were screaming and telling the people behind the counter, you know, open up the registers. >> the camera shows the thieves emptying the cash register, but they have their eyes on an even bigger prize. >> i didn't think anyone's life was in danger until they asked one of our waitresses to unlock our drop box under the register. no one who works the night shift has a key to the drop box. that's the only time i ever got scared for anybody, because they seemed to think someone there did have a key. >> unable to get it open, the gunmen leave without the money from the drop box, but they still escape with around $2,000 in cash. >> i was still face down. they took mostly everything from everybody out of there. felt like to me, felt like death. that's what it felt like to me.

>> after the robbers leave, one victim decides to take the law into his own hands. the surveillance footage shows the man running to his car to grab a gun. he darts across the parking lot followed by another customer and shoots in the direction of the fleeing robbers. >> i wasn't out there to see who was shooting at who, but i know i heard commotion. >> i heard gunshots outside after the robbery. >> despite the customer's effort to stop them, the three armed men escape. someone in the restaurant calls the police. they arrive at the waffle house shortly after the incident and take statements from the stunned customers. >> it's not an everyday occurrence where 16 people are robbed at once. >> jeff braden is with the houston police department and is the lead investigator on the case. he can see from the surveillance tape that the robbery is well planned. >> they were very strategic in how it played out. one suspect stood by the door

and the other suspect handled the kitchen area and went back to where the cooks were and the other suspect went to the other side of the waffle house to handle those people. everybody had a plan. >> other than the video, the masked robbers leave little evidence for detectives to follow. >> two of the three had gloves on and they made it difficult for us to be able to retrieve any kind of dna evidence simply because the fact that they just simply didn't leave any behind. >> two weeks after the robbery, detective breeden receives a call from the harris county police department. >> a suspect was arrested in an unrelated robbery in harris county and our guys obtained the initial confession. he was the individual carrying the rifle during the robbery. he gave us two additional names as suspects. >> neither suspect pans out.

one of the men has an alibi, and witnesses can't identify the other suspect out of a lineup. so far, no one is charged with the waffle house robbery, even the man who confessed. >> being that he was in charge in this particular case and he was charged in other cases that were much stronger or we had a better case on him. >> with the case at a standstill and with the surveillance video available to watch on youtube, both mitchell and cole say they're having a difficult time putting the terrifying experience behind them. >> it kind of makes you have a different perspective on life. if something happens to me, who is going to take care of my son? nobody is going to love your child or take care of your child the way that you take care of them. >> i go to the store, get a tank of gas or buy coke or chips and buy groceries and then i think somebody is going to rob me. >> you sit there and you watch it and you think, what would i do? so it makes you think. coming up -- a seemingly mild-mannered jewelry store owner surprises two armed men when they try to hold up his shop. >> this is a real deal.

this is an automatic and now i have got to kill these guys. >> when "caught on camera: armed and dangerous" continues. i take pictures of sunrises, but with my back pain i couldn't sleep and get up in time. then i found aleve pm. aleve pm is the only one to combine a safe sleep aid plus the 12 hour pain relieving strength of aleve. i'm back. aleve pm for a better am.

over two hundred years of citi history matter to you? well, because it tells us something powerful about progress: that whether times are good or bad, people and their ideas will continue to move the world forward. as long as they have someone to believe in them. citi financed the transatlantic cable that connected continents. and the panama canal, that made our world a smaller place. we backed the marshall plan that helped europe regain its strength. and pioneered the atm, for cash, anytime. for over two centuries we've supported dreams like these, and the people and companies behind them. so why should that matter to you? because, today, we are still helping progress makers turn their ideas into reality. and the next great idea could be yours.

a store owner turns the tables on two armed men when he pulls out a gun to defend himself. >> probably figured that come into my store and such a nerd, if i pulled a gun, he'd probably just faint. >> february 14th, 2005. it's a few minutes before 9:00 a.m. in bardonia, new york, a town 35 miles north of new york city. barry fixler is about to open his jewelry store for the annual valentine's day rush. >> gentlemen come in from 9:00 in the morning until about 8:00 at night to pick up a heart real quick, engagement ring real quick either for their girlfriend, fiancee or wife.

>> so, when two men show up at the door a little early, barry doesn't think twice about letting them into the shop. >> i open the door and they followed me in the store and went around the counter and one fellow says, i'd like to see engagement rings. >> the man in the black coat stares into the display case and singles one out. a routine fixler has seen thousands of times. >> figured this is just a normal sale. the other fellow actually joked around and said that, i'm trying to talk my buddy out of this. it was sort of a joke. >> fixler hands the man a diamond ring. he examines the ring closely, as if he's considering buying it. but fixler senses something is off. >> i see that he was hesitating and the price tag of that ring was $14,000. so i figured to myself, maybe that price is a little too much. >> as fixler and the man talk, something unexpected happens. >> what comes in my face is an

automatic pistol. >> the gunman demands money, but fixler has no intention of giving in to his threats. the robbers don't realize it yet, but the unassuming shop keeper is not as defenseless as he appears. >> my brain went into, this is the real deal. this is an automatic. do not like automatics and now i got to kill these guys. i pushed the weapon out of my face, i bolted about eight, ten feet to where i have my revolver hidden, took it out of the holster and came up, pointed guns at each other and i just fired away. >> fixler aims at point-blank range and shoots both men in the chest. the dramatic moment is played out in front of the store's surveillance camera. >> as you view the surveillance tape, you could see him cursing, i'll kill you, i'll kill, i'll kill you. now he's mad at me. he probably thought i just ran to duck underneath the counter and a scaredy-cat, not knowing that i'm armed.

as i went around the counter i shot the other fellow who was also armed, in the side of the chest. he goes down and both go down. the fellow i shot at the first time got up and stepped over his so-called partner to race out of the store. >> the man in black escapes unharmed because he's wearing a bulletproof vest. but the man on the ground is badly wounded. it turns out he isn't wearing one. >> his partner was shot in the side. his spinal cord severed, but actually makes it to my door and collapses. >> the man in the black coat, who had just high-tailed it out of the store, jumps into a brown minivan, the get-away car, and screeches out of the parking lot, leaving the second man behind. the clarkstown police department responds within minutes. when detective bill fritz arrives he finds fixler, pistol

in hand, standing in a defensive position and screaming at the man on the ground. >> i think he was in fear of his life. i think he believed at the time that they were going to shoot him. he just kept repeating that he couldn't believe that it happened to him. >> the man in the black coat who jumped into the getaway car is matthew ross. he's eventually captured, convicted of attempted robbery, and sentenced to ten years in prison. the man in the white hoodie, joseph nipper, is also convicted of attempted robbery but dies two years after the shooting from complications from his wounds. what ross and nipper didn't know that day is that fixler is a combat veteran who fought in vietnam and not the nerdy, easy target they expected. >> they probably figured i'm the last guy to know how to use a weapon. >> fixler is not charged with any crime. he legally possessed the handgun he used. and with the help of the videotape, police determined he had the right to defend himself because he was in fear for his life. after the robbery, fixler receives an outpouring of

support from the community and wants to find a way to give back. >> i'm in this community for 20 years and business for over 20 years. they know that i just came from a life and death situation. >> the retired marine starts by helping local war veterans, including sergeant eddie ryan who was wounded in the iraq war. >> sergeant ryan sustained a head injury in battle, and in learning of this, barry fixler donated the profits from his store following valentine's day to the family so they could make some repairs or changes to the house to so they could accommodate their son. >> sergeant eddie ryan's parents are grateful for the help that fixler has given them. >> i could never repay this guy for what he's done for us. he doesn't want payment. he just wants to do it for eddie. he says eddie did it for us, and i'm doing it for eddie. >> fixler also writes a book about the robbery and his

vietnam experience called "semper cool" and donates all royalties to wounded veterans through the barry fixler foundation. >> i want to honor the men and women serving today. the men and women serving when i was in service. and, also, to leave a legacy to my family that, you know what, i'm a good guy. i love my family and i love my country. >> the retired marine continues to run his jewelry store. always mindful of the day two gunmen tried to rob him. >> i looked like a very easygoing fellow. non-threat fellow, nerdy. they really came thinking that this is going to be a cake walk. this is the easiest thing ever. and it turned out not to be the easiest thing ever. coming up -- a store manager who never fired a gun in her life ends a robbery with one shot. >> got up like i was coming around and i grabbed the gun. >> when "caught on camera: armed and dangerous" continues.

a man claiming to have a gun holds up this gas station

convenience store and demands cash. fearing for her life, the store manager pulls out a gun and shoots him. >> lord, just let me take him with me, if he's going to kill me. >> december 8th, 2004, columbus, ohio. karen smith arrives at work kbloe early in the morning at the kb sunoco gas station and convenience store. as manager, it's her job to get the store ready for the day's business. >> he came in and i looked at him. >> smith sits behind the counter waiting for the man to speak. >> he stuck his hands in his pocket and he leaned on the counter, and he had his fist on the counter, and says, you know what i'm here for. >> unfortunately, smith knows exactly what he means. the store has been held up many times, but this frightening experience is caught on the store's surveillance camera. >> the last ten years i was getting robbed like every month.

they would come in and stick me up. i'd give them the money and they'd run out. >> smith is surprisingly calm. although she's not 100% sure the man has a gun, she doesn't take any chances. >> so i gave him everything out of the drawer. >> but this robbery isn't like the other hit and run stickups that she's experienced. this guy wants more. >> he wouldn't leave. and he asked me to come from behind the counter. i said, what for? you already got all the money. what else do you want? >> smith braces herself for his answer, but he never gives one. frightened for her life, smith panics and makes the split-second decision to defend herself. >> i got scared then. i figured, he was going to hurt me. i got up like i was coming around, then i grabbed the gun. shot at him.

>> smith has endured being robbed time and time again. but this time the no-nonsense store manager, who has never fired a gun in her life, shoots the man. one time, at point-blank range. >> i didn't realize i hit him at first because it took a minute. >> now, armed with a little more courage, smith makes sure the robber doesn't try to hurt her. >> don't move. >> i was scared. i said, hey, show me your hands and he said, i don't have anything. >> it turns out the robber doesn't have a gun. smith is both relieved and annoyed. the robber pleads with her. >> please, don't shoot me. call 911. >> in a dramatic turn of events, it's the robber who's now afraid for his life. >> he was squirming around on the floor and i said, you weren't thinking about 911 when you was robbing me.

shut up. i'll call them. >> smith keeps the gun aimed at the robber until police arrive. >> i was so relieved when they came. it was like, thank you, god, for not letting me kill this man. he didn't have no gun, but i was so terrified of him hurting me, i was like -- me or you, babe. >> the robber is 26-year-old desmond thompson. the bullet that hits him goes through his arm but he's able to make a full recovery. he's convicted of second degree robbery and sentenced to five years probation. as for smith, the franklin county sheriff's office concludes that she acted in self-defense and no charges are filed in the shooting. and while it took nerve to defend herself in the heat of the moment, it's months before she actually gets up the courage to watch the robbery on videotape. >> when i first saw it, it was weird. it just brought back bad villains for me.

>> for added security, the owner of the gas station installs a new bulletproof partition in front of the counter to protect employees. smith does not want to be known for shooting someone, but she is proud that she defended herself. >> i was not going to let him hurt me. i would have did whatever i had to do. i was so terrified that he was going to hurt me. and that's why i shot him. april 4th, 1997, seattle, washington. armed with a sword, a mentally ill man starts an 11-hour standoff with police. dressed in a black jacket, camouflage pants and dark shades, tony allison wields a samurai sword in a busy intersection. cornered, the man refuses to surrender his weapon without a fight. allison says he's possessed by the devil, and is ready to kill the demons who haunt him. >> talked about his name being

apollo. he talked about satan. he talked about his brothers in russia and china. but he never really engaged the negotiator. >> the spectacle draws a crowd of onlookers and captures the attention of local news station. they record allison brandishing his sword with no sign of letting up. during the course of the standoff police attempt several nonlethal strategies from rubber bullets to pepper spray and mace. but nothing deters him. after 11 hours the police try one more approach. they use a fire house to spray allison with cold water, hoping that he will lose his grip on the sword. when that doesn't work, they turn the water pressure up full blast. allison loses his balance and falls to the ground. police officers use a ladder to

subdue him, then pry the sword from his hand. after the intense standoff, the man is taken to a mental hospital with minor bruises. he is not charged with a crime. coming up, surveillance cameras capture a violent attempt to hold up a convenience store. >> the video was crazy. i was shocked to see it the way it went down. >> when "caught on camera: armed and dangerous" continues. this is the one place we're not afraid to fail. some of these experiments may not work. but a few might shape the future. like turning algae into biofuel... ...new technology for capturing co2 emissions... ...and cars twice as efficient as the average car today. ideas exxonmobil scientists are working on to make energy go further... ...no matter how many tries it takes. energy lives here.

you're all set to book a flight using your airline credit card miles. and surprise! those seats sometimes cost a ridiculous number of miles, making it really hard to book the flight you want. luckily, there's a better way... with the capital one venture card. hi. i'm richard lui. we interrupt scheduled programming to listen to the president making remarks on the climate change summit in paris. >> -- protecting this planet for future generations. two weeks ago in paris i said before the world that we needed a strong global agreement to accomplish this goal. an enduring agreement that reduces global carbon pollution and sets the world on a course to a low carbon future. a few hours ago we succeeded. we came together around a strong agreement the world needed. we met the moment.

i want to commend president hollande and secretary general for their leadership and for hosting such a successful summit and for the foreign minister residing with patience and resolve. i want to give a special thanks to secretary john kerry, my senior advice viseadviser, our negotiator and everyone on their teams for their outstanding work and for making america proud. i also want to thank the people of nearly 200 nations, large and small, developed and developing, for working together to confront a threat to the people of all nations. together we've shown what's possible when the world stands as one. today the american people can be proud because this historic agreement is a tribute to american leadership. over the past seven years we've transformed the united states into the global leader in fighting climate change.

in 2009 we helped salvage a chaotic copenhagen summit and established the principle that all countries had a role to play in combatting climate change. we then led by example with historic investments in growing industries like wind and solar, creating a new and steady stream of middle class jobs. we've set the first ever nationwide standards to limit the amount of carbon pollution power plants can dump into the air our children breathe. from alaska to the gulf coast to the great plains we've partnered with local leaders who are working to help their communities protect themselves from some of the most immediate impacts of a changing climate. skeptics said these actions would kill jobs. instead we've seen the longest streak of private sector job creation in our history. we've driven our economic output to all-time highs while driving our carbon pollution down to its

lowest level in nearly two decades. and then with our historic joint announcement with china last year, we showed it was possible to bridge the old divides between developed and developing nations that had stimied global progress for so long. that accomplishment encouraged dozens and dozens of other nations to set their own ambitious climate targets. and that was the foundation for success in paris. because no nation, not even one as powerful as ours can solve this challenge alone. and no country no matter how small can sit on the sidelines. all of us had to solve it together. now, no agreement is perfect including this one. negotiations that involve nearly 200 nations are always challenging. even if all the initial targets set in paris are met, we'll only be part of the way there when it comes to reducing carbon from

the atmosphere. so we cannot be complacent because of today's agreement. the problem's not solved because of this accord. but make no mistake the paris agreement establishes the enduring framework the world needs to solve the climate crisis. it creates the mechanism, the architecture for us to continually tackle this problem in an effective way. this agreement is ambitious with every nation setting and committing to their own specific targets even as we take into account differences among nations, we'll have a strong system of transparency including periodic reviews and independent assessments to help hold every country accountable for meeting its commitments. as technology advances, this agreement allows progress to pave the way for even more ambitious targets over time. and we have secured a broader commitment to support the most

vulnerable countries as they pursue cleaner economic growth. in short, this agreement will mean less of the carbon pollution that threatens our planet and more of the jobs and economic growth driven by low carbon investment. full implementation of this agreement will help delay or avoid some of the worst consequences of climate change and will pave the way for even more progress in successive stages over the coming years. moreover, this agreement sends a powerful signal that the world is firmly committed to a low carbon future. and that has the potential to unleash investment and innovation in clean energy at a scale we've never seen before. the targets we've set are bold and by empowering businesses, scientists, engineers, workers and the private sector, investors, to work together, this agreement represents the best chance we've had to save

the one planet that we've got. so i believe this moment can be a turning point for the world. we've shown that the world has both the will and the ability to take on this challenge. it won't be easy. progress won't always come quick. we cannot be complacent. while our generation will see some of the benefits of building a clean energy economy, jobs created, money saved, we may not live to see the full realization of our achievement, but that's okay. what matters is that today we can be more confident that this planet is going to be in better shape for the next generation. and that's what i care about. i imagine taking my grand kids, if i'm lucky enough to have some, to the park some day and holding their hands and hearing their laughter and watching a quiet sunset all the while

knowing that our work today prevented an alternate future that could have been grim. that our work here and now give future generations cleaner air and cleaner water and a more sustainable planet. and what could be more important than that? today thanks to strong principled american leadership, that's the world we'll leave to our children, a world that is safer and more secure, more prosperous and more free. and that is our most important mission in our short time here on this earth. thanks. >> president obama spending six minutes definitely saying the important role that the united states have taken in the what is so-called the paris agreement, the document the result of five sets of grueling negotiations

this year. let's go to kristen welker who has been with us listening. reaction so far because we've just had this newly christened deal, shall we say here, kristen, within the last several hours. >> reporter: look, there will be some critics to this deal. reaction pouring in as we speak, richard, but there's no doubt this is a major win for president obama. as you well know he has made climate change one of his key second term priorities. and what this deal really does it allows him to say he's advanced that part of his agenda. now, the president has been working the phones we can tell you behind the scenes from washington this past week he's been calling leaders from france, brazil, china and india to press them to get this done. and while the deal is ambitious it also reflects number of concessions on the part of the united states. president obama for example didn't call for uniform can you want -- cuts to greenhouse gas emissions or a carbon tax very difficult to get through the republican-led congress. and the deal relies on countries to make individual pledges.

you heard him talking about that with some nations receiving financial help from the larger ones for example. senior administration officials say it sets the table for more efforts in the future. we're getting more reaction from the 2016 campaign trail. bernie sanders slamming the deal saying it doesn't go far enough. hillary clinton saying this is an historic and important first step, richard. >> kristen welker at the white house. the president just spending six minutes at the white house congratulating what has happened, what has been achieved in paris. we'll continue to follow developments and reactions coming from not only washington, d.c. but the united states in and around --. platinum-based chemotherapy, it's not every day something this big comes along. a chance to live longer with... opdivo, nivolumab. opdivo is the first and only immunotherapy fda approved based on a clinical trial demonstrating longer life... ...for these patients. in fact, opdivo significantly increased

the chance of living longer versus chemotherapy. opdivo is different. it works with your immune system. opdivo can cause your immune system to attack normal organs and tissues in your body and affect how they work. this may happen any time during or after treatment has ended, and may become serious and lead to death. see your doctor right away if you experience new or worsening cough; chest pain; shortness of breath; diarrhea; severe stomach pain or tenderness; severe nausea or vomiting; loss of appetite;... ...swollen ankles; extreme fatigue; constipation; rash; or muscle or joint pain, as this may keep these problems from becoming more serious. these are not all the possible side effects of opdivo. tell your doctor about all your medical conditions including immune system problems or if you've had an organ transplant, or lung, breathing or liver problems. a chance to live longer. ask your doctor if opdivo is right for you. bristol-myers squibb thanks the patients and physicians who participated in the opdivo clinical trial.

this holiday season, gewhat's in the trunk? nothing. romance. 18 inch alloys. you remembered. family fun. everybody squeeze in. don't block anyone. and non-stop action. noooooooo! it's the event you don't want to miss. it's the season of audi sales event. get up to a $2,500 bonus for highly qualified lessees on select audi models. a police s.w.a.t team confronts a man armed with a loaded handgun. >> when i first arrived on the scene he was demanding that the police shoot him.

>> but the intense standoff ends with an incredible shot by one of their snipers. april 15th, 2004, atlanta, georgia. a man calls 911 and in a calm voice reports a dire situation. >> yes, there's a man with a gun in the save rite parking lot. >> okay, who has the gun? >> me. >> the man on the line is 51-year-old steven gittens. he's recently divorced and homeless, and now he's armed and dangerous. >> what are you planning on doing with the gun? >> hopefully i'm going to shoot me. >> he tells the 911 operator that he's going to kill himself. and in his unstable condition, police are concerned he may shoot others, as well. the standoff takes place in the parking lot of a big supermarket, which draws a crowd of bystanders, as well as a local news crew.

the situation is tense. mark mcgann, a clayton county detective and s.w.a.t team member responds to the 911 call, along with several dozen other cops. >> i could see his face and my impression was that he was very calm and that's not unusual for someone who has decided to commit suicide. often a state of calmness comes into play because they have made their decision. >> but if he wants to commit suicide, why does he stage such a spectacle in a public place? >> we already knew from what he had told the 911 dispatcher that he wanted the police to shoot him. almost all police officers receive training in that phenomenon, of suicide by cop. >> the officers negotiate, but gittens wants police to shoot him. >> fortunately in my career in 34 years in law enforcement, i never had to shoot someone and that was really the very first day in my entire career i was faced with that possibility. my adrenaline was up simply from that perspective. >> gittens isn't giving up.

and police need to end the standoff before anyone gets hurt. mcgann and the s.w.a.t. team snipers come up with a bold plan. >> apparently the man laid the gun down once and picked it up, again. the plan as the chief formulated it was to negotiator would talk the man into putting the gun down again, at that point we would try to take a shot on the weapon. >> if the plan fails, it could provoke him to shoot himself or fire at police. detective mcgann, armed with his mcmillan .308 caliber rifle braces himself on the back end of a pickup truck about 65 yards away. his finger is on the trigger and his eye is on the scope. >> you look through the scope and your field of vision is very narrowed. i sighted on the gentleman initially although we were there to take a shot on the weapon, the possibility always existed

that we would have to take a shot on the individual, depending on what he did. >> mcgann hopes he doesn't have to shoot gittens but is ready for whatever action he's ordered to take. >> about an hour and 35 minutes in to the negotiation, the chief asked if we could take a shot, how confident we felt about that. the spotter, sergeant toro turned to me and said the chief wants to know if you're 100. and i joked to sergeant toro, i said no, tell the chief i'm 110%. >> the gun is on the hood of the truck, but gittens hovers within an arm's reach. >> at that point, i received a communication from the s.w.a.t. team commander to take a shot. >> a perfect shot. mcgann shoots the gun right off the hood of the truck. it flies 20 feet beyond the vehicle and lands on the ground. >> i wanted to take the shot as quickly as i could. i put the crosshairs on the gun and understanding my weapon, i lowered the cross hairs just very slightly and fired at the weapon. what's ironic about this situation, i never heard the shot.

to this day, it's amazing because i wasn't wearing ear protection and even though i was looking through the scope, i never saw the gun go off the truck. i guess you focus so much on what you're doing that you block other things out. i immediately came off the gun and called the s.w.a.t. team members that were moving towards him, and that i realized that the shot had been successful. >> just moments after police take gittens into custody, a local news crew captures mcgann's reaction to his once in a lifetime shot. >> the way i fired, i fired right onto the gun so the round went into the car. there was never any chance of him being hit. i feel well about the shot. i got good equipment, i was trained well, good s.w.a.t team and we had the people here today to make the right decision. >> gittens is arrested and given a psychological evaluation. when police search his truck, they find a letter that states, i think about killing myself,

but i don't seem to have the guts to do it. maybe i can get the police to shoot me and then this will all be over. gittens doesn't get his wish that day. he's convicted of reckless conduct and sentenced to three years probation. gittens dies almost six years later. he was 56 years old. captain mcgann kept the handgun that he shot off the truck as a solemn reminder of that day. >> this is the handgun that mr. gittens had. it's a small caliber, .380. the gun at the point i shot it was laying on the car in this position. and the round struck the weapon in the downward angle and point of impact is right here, but the bullet, after striking the handgun, went into the engine compartment of the vehicle and disintegrated. >> mcgann attributes the successful outcome of the standoff to his years of police training.

a store clerk fights for his life after being stabbed in the neck during a bold daytime robbery. but even after the thief gets the money, he continues his violent assault. >> he took the money and he told me to follow me, otherwise i'm going to cut your throat, again.

>> august 7, 2011. daytona beach, florida. a place known for its sun, sand and international speedway, but like a lot of tourist hot spots, there exists a seedy and dark underside. >> daytona attracts a lot of transient people, and so along with the people that want to come here and enjoy daytona, we also have the criminal element that wants to come, also, and prey on the visitors that come here. but it's not just the visitors here who fall victim to crime. >> i'm working alone here in the store and it was 3:00. everything is fine. >> an immigrant from bangladesh moves his family from new york to daytona beach to get away from the cold. but the sun and surf are no protection against what happens on that beautiful summer day at the valero gas station and convenience store. >> i was fixing the newspaper

and one guy opened the door and came right behind me and put knife here. >> udon can't believe what is happening to him. he fights back, but the knife wielding robber quickly gains the upper hand and threatens udon. >> told me, don't talk, don't move. if you move, i will cut your throat. >> holding him at knife point, the thief orders him to go behind the counter and open the cash register. the clerk tries to comply, but is so terrified that he can't do it. >> i don't know. i was scared. i was shaking, and i cannot open the register. he tried to beat me and stab me in the neck, i was totally out of mind. >> fearing for his life, he fights to pry the weapon from the thief's hand, but is unable. >> kicking me, punching me. >> as the two men continue to brawl, udon is stabbed in the

neck. >> he stabbed here. >> with the knife still pointed at him, the two men make their way back to the register. >> finally, i open the register. >> as the drawer opens, the thief takes about $500. knowing he has to act fast, udon quietly reaches for a baseball bat in the corner. the thief catches udon and then lunges at him before he can take a swing. as they continue to fight, udon drops the bat. in desperation, he grabs the back of the thief's neck with one hand and tries to push away the knife with the other. in a momentary stalemate, udon is able to pick up the bat off the floor, but the thief wrestles it away. >> he took the baseball and hit me in the head, neck, shoulder, everywhere. and he broke the counter, everything.

>> even though the thief has gotten the money, he doesn't leave. he continues to fight to get the upper hand, but the clerk resists and the two men tussle their way from behind the counter. they've been fighting off and on now for 2 1/2 minutes and continue to exchange blows. the battle finally ends when the thief bolts into the street. >> we received the call of an armed robbery, aggravated battery. the clerk was injured. he had been stabbed and was bleeding. >> police secure the surveillance video from the seven cameras installed in the store. >> after we obtained the video, we let all the news organization know that we had the video on the website and the news organizations throughout carried this on their evening news. and we started receiving phone calls. >> the release of the video quickly pays off.

a suspect, charles shelling, is apprehended within three days. >> we received several tips as to who he was and then after we got him identified, then we received another phone call telling that we could go to the 200 block in daytona and we went there and he was there and he was placed under arrest. >> shelling is shown the video and makes the surprising statement to police. >> yeah, that's me on the video. but i don't remember doing any of this. >> shelling claims he doesn't remember robbing the store or stabbing udon, because he didn't take his medication that day. but the videotape is vivid proof. >> the video is one of the best evidence, like in dna or fingerprints. >> this is not the only time shelling is caught on a surveillance camera committing a crime. earlier that same day, this surveillance video captures shelling robbing a kangaroo express store in daytona beach. >> the clerk greets him with a

pleasantry and a smile and all of a sudden the guy pulls out a knife and jumped the counter. and you could see the reaction from the clerk that she's scared. but she complies with whatever he told her. he got the money and within a couple of minutes he was out the door with the money. >> both the clerk at the kangaroo express store and udon are lucky to have survived the robberies. the doctors who treat udon tell him that if the knife had gone any deeper, it could have killed him. >> if he would have hit one of those major arteries, it would have been all over and we would have been working a homicide. >> charles shelling is convicted of robbery and aggravated assault in both cases. he is sentenced to 20 years. >> the video played a really important part in solving this crime, but there's a possibility that just with the description alone, we may have caught this guy anyway.

but the video helped us tremendously. >> as for udon, he counts his blessings every day. despite the violent attack, he goes back to work at the convenience store, though his children wish he would quit. >> come on, please, don't go there. every day, can you quit the job? can you find another job? >> but udon says he won't leave any time soon. he's grateful to have this job, at least for now. >> i came back. owner, he trust me. he help me lot of different way. money, financial, and mental support. everything he gave me. >> being a victim of an armed robbery didn't deter udon from returning to his job and didn't deter store manager karen smith or jewelry store owner barry fixler, either. they all went back to their daily lives, knowing that when they were faced with fear, they

fought back. a rampaging elephant. >> i probably should have died that day. >> a runaway cadillac. >> i initially thought someone threw a bomb through the front door. >> and a terrifying earthquake. >> i'm thinking i don't know if i'll get to the bottom of the stairwell. >> on the job nightmares caught on camera. >> watch out for the chimney. >> some end with a crash. >> stand back now. >> others are blown away. and sometimes broadcast on live tv. >> i didn't know what to do. >> but hey, it's no use crying over spilled wine bottles. nine to fivers who weather the
