ify it. we will see how long that works. thanks for being with me and happy fourth. i'm brianna keilar in "the situation room." thank you for watching. to our viewers here in the united states happy fourth of july. newsroom with kate baldwin starts right now. next america on alert. law enforcement ramped up across the country. 7,000 extra officers armed and ready in new york city. all on guard against a possible july 4th terror attack. richard matt's final letter to his daughter. did officials miss a big clue that could have stopped the escape? this is one big fish tale with the video to back it up. he ends up in the water with a shark. he is joining us live. good evening, everyone.

i'm kate baldwin. you are watching a special edition of cnn newsroom. federal, state and local law enforcement around the country, many heavily armed and on guard against possible terror attacks this holiday weekend. security and surveillance ramped up at holiday celebrations and large events. one official warning there has been an increase of terrorist chatter. 3 million people are expected to attend an event in new york city. an additional 7,000 nypd officers will be on hand backing up thousands of regular patrols. thousands of surveillance cameras will make up the city'sizecity's ize eyes in the sky on downtown new york. in the nation's capital, another high value target for terrorists 700,000 visitors are expected along the national mall alone. jim sciutto is in washington tonight watching it all. what's the biggest concern right now? >> reporter: lone-wolf

terrorists.terrorist s s. it's harder to track them. the trouble then is without any specific threat that authorities around the country have to protect everywhere as many places as they can, particularly prominent targets. it's a real challenge. it's one of so many law enforcement communities are facing across the country this weekend. in new york city today, ramped up security ahead of fourth of july fireworks. andrew cuomo announcing new plans to enhance monitoring of celebrations across new york state. this is the new normal across the country. increased security at july fourth events from los angeles to washington to philadelphia. communities big and small respond to an fbi bulletin warning of potential lone-wolf attacks, timed to the holiday weekend. >> we know a, there are a lot

of travellers b, transportation has been and is a target of some of the groups and, c, we see increasing number of attacks, especially large crowd gathering. >> reporter: the state of alert extends to americans overseas. the state department ordering all diplomatic posts to review security. behind the threat a call to arms from isis to supporters around the globe to attack wherever and however they can. this during the muslim holy month through the middle of july. the terror group's list of american recruits and sympathizers growing by the week with nearly 50 charged since the start of the year. >> all they are trying to do now is to inspire one or two or a small number of individuals to conduct attacks. it begs people do this in the west in the u.s. in europe in north africa. people are now listening. >> reporter: the u.s. is not alone in facing the threat of isis-inspired attacks.

the uk carried out a realistic counterterrorism drill with more than 1,000 emergency personnel earlier this week. this is the bodies of 30 british citizens gunned down by an isis supporter in tunisia last week arrived home by military escort. another challenge. you hear how groups like isis take advantage of social media. they do, both to radicalize and to activate plots overseas. more and more of the community is taking place through encryption. that makes it impossible very difficult for counter terror authorities to catch the plots, to catch the things. it's a real challenge for them going forward. it's one of the many challenges they are facing this weekend. >> it lays to bear the challenge they face. law enforcement need to be right 100% of the time. terrorists they need to be right once. great to see you. thank you. one major focus for law enforcement tonight is

protecting soft targets, where crowds gather, malls, monuments or holiday celebrations where the public is vulnerable to attacks. rene marsh is on the national mall. what plans do law enforcement have in place there to keep everyone safe tonight? >> reporter: kate we have been out here all day. i can tell you what i'm seeing here for myself. the perimeter here around the capital extends three blocks. we're seeing miles and miles of fencing as well as concrete as well as metal barriers. they have been erected around the national mall. we know capitol hill police have placed all of their officers throughout the grounds here on the capitol. we have seen k-9 units making their rounds around here today. that is the feeling. that's the atmosphere here on the day before the fourth of july. you mentioned those soft targets, the bridges, tunnels,

the train stations. those areas are really difficult to police or even to protect in the sense that you often times have thousands of and thousands of people at any given moment going over or through these soft targets. despite the challenge, we are seeing more of a law enforcement presence more bomb sniffing dogs at these locations as they prepare for the crowds for the fourth of july. >> you can hear behind you what sounds like rehearsals behind you going on in the west front. thank you very much. joining me to discuss the threat -- the broader threat and the threat this weekend, cnn terror ism terrorism analyst. let's take new york as an example. it's always a terror target. at least 3 million people are expected to attend the fireworks show this weekend. even with all hands on deck can

they be 100% secure and still put on an event like this? >> no absolutely not, kate. you can't -- 3 million people you can't protect. we don't run a police state. it's too many people. the weapons of mass murder are too easy to make. that doesn't even bring up the question of automatic weapons like used in tee knees yaunisia. what they are doing now is running through all the leads and who potentially could turn to violence at this point. again, as we have been talking about, it's the lone wolf who hasn't come up on social media, has access to weapons and can pretty well hit where he likes and when he likes. >> that's the unfortunate truth. with all of the security precautions that have been announced, can anything really -- to bob's point, prevent a lone wolf who wants to carry out an attack? >> kate once they are moving towards launching an attack

very difficult to prevent. there are almost an unlimited number of soft targets. you can't protect everywhere at once. isis are calling on their supporters to attack anyone anywhere at any time. so these attacks could occur with very very little warning. what the fbi is focusing on is trying to identify people of concern before they are able to move forward and launch an attack. they are scouring social media. they arrested 12 americans who were plotting to carry out attacks. very concerning. the excelaccelerateing number of americans getting involved. >> paul what's the draw then? this is kind of the question that's been in the back of my mind. what's the draw to attack around the holiday like this when these terror groups they have to be aware at this point that law enforcement is on high alert? >> kate terror groups have had a longstanding ambition to hit

the united states on national holidays. they realize that that would inflict additional psychological trauma. documents found in bin laden's area showed al qaeda was interested in attacks united states on july 4. i think we need to look beyond july 4 to ramadan. followers around the world will be rewarded tenfold if they launch attacked during ramadan. it ain't go going away after the july 4 weekend. >> that's for sure. seems like the new normal. we are hearing so much from officials about what extra measures they are putting in place. who is the audience that officials are speaking to in laying this out? is it the public to say we're on it? is it the potential terrorists to say, beware? >> it's the police first of all, the local police are the first line of defense. they have to be looking for leads, stopping cars randomly

looking for people out of place. this kind of threat has to go out to the american people because it's the american people that are ultimately the target. it doesn't do to keep these things secret. i think when the fbi releases a threat like this or homeland security they're very serious about it. i have never seen a higher alert since 9/11. >> i have heard that from more than one person. it's unsettling. paul what you are speaking about a little earlier, officials saying that the current isis threat it's evolved in such a way that having credible intelligence before a terrorist attack it seems to be growing increasingly difficult because there's so many different methods that they reach out. then what is the biggest challenge for intelligence officials in identifying threat inging threat threats? >> there has been a growth in social media, a volume that the fbi is having to go through. difficult to tell who is a radical blow hard and who will

move forward to launch an attack. as jim was mentioning another concern is the fact they are using encryption on the online messaging apps to instigate attack attacks. isis fighters have been using to correspond with followers in the west. they have been using it now in the last few weeks to actually provide bomb making guidance to potential lone wolves. all this worrying to western law enforcement officials. >> it adds up. it's all very worrying. we're heading into the holiday. as you both are pointing out, it extends beyond that as ramadan continues. thank you very much. have a great fourth. coming up donald trump is just two weeks -- in just two weeks he has gone from real estate mogul and reality show star to a top gop presidential contender in the poles. is it despite or because of his inflammatory language? we're learning more about convicted killer richard matt's

spotlight. donald trump continues to rise in the polls despite losing support from his business partners because, again, of this. >> when mexico sends its people they are not sending their best. they are bringing cape. they are rapists. >> you don't have any regrets? >> some are good. some are rapists. some are killers. we don't know what we're getting. no apology because everything i said is 100% correct. >> now one republican presidential candidate is trying to lead the charge and fight back. he is someone who trump once called a friend. >> reporter: former new york governor george pataki launched a petition to stand up to trump. >> these comments about mexicans that are so divisive. he is wrong. >> reporter: trump firing back calling him a terrible governor

of new york who couldn't be elected dog catcher if he ran again. a change of heart from when he was governor and trump donated to his campaign. companies doing business with trump appear to agree with the former new york governor cutting ties with the real estate mogul over the controversial comments made at his campaign announcement. >> they are bringing drugs. they are bringing crime. they are rapists and some i assume are good people. >> reporter: macy's saying they will no longer sell trump clothing. nbc universal and univision backing out of the pageants. >> what they did to these young women was disgraceful. they never had them in mind. >> reporter: even the chief executive of reelz that picked up the pageant dismissed the donald's remarks. >> i agree with everything nbc and univision and macy's is saying. >> reporter: former contestants

rejecting his rhetoric. >> it's dangerous to generalize a population and attribute such hateful comments to them. >> reporter: trump remains steadfast in his position saying his statement was backed up by a report about central american women being raped while traveling to the border. >> all you have to do is go to fusion and pick up the stories on rape. >> that's about women being raped. it's not about criminals coming across the border entering the country. >> somebody is doing the raping. >> reporter: trump has surged in the polls, up to second place nationally and in the early voting states of iowa and new hampshire. tonight, donald trump is claiming new evidence for his controversial stance on mexican immigrants in the tragic murder of a young woman in san francisco who was gunned down while on a walk with her father. the man accused in the case is reported to be an undocumented

mexican immigrant himself. trump saying tonight, this senseless and totally preventable act of violence committed by an illegal immigrant is yet another example of why we must secure our border immediately. kate? >> donald trump not backing down even tonight. joe johns, thank you so much. joining me now to discuss, ben ferguson and rick wilson. ben, to you. it seems -- you and i have discussed this. it seems the gop presidential candidates the other ones they haven't wanted to take on trump at all, unless they are forced to. at this point, are the campaigns now having to come up with a trump strategy? >> yes. but i think it's going to be one very covert. it's not going to be with the candidate coming out and going after donald trump directly. i think what you will see is the campaigns will do their research. they will find a lot of the dirty laundry and give that out to different people in the media and pushing it out there. because ultimately they don't

want to be seen as going toe to toe with donald because they think he is beneath them. he's a side show he is not a legitimate candidate. they just want to get this to go away as fast as they possibly can. so that's how they will start to deal with him. >> rick, trump is happy to take them on. listen to this. >> i think bush is an unhappy person. i think he's highly overrated. he's an overrated person. chris will get good publicity. that's okay. it's not going to make any difference. >> i'm sure give him another week and they will all be in that. trump could end up -- this is the important part. despite all of this it looks like trump could end up on the debate stage. if so how do they take him on without getting drawn into his circus? >> there are two people that are going to make that final decision. these folks have to make a

decision if they want to turn the republican debates into a clown show. that's what's going to happen. you will have donald trump on that stage. he will make -- the things he will do will make his comments about mexican immigrants look like child's play. he will turn the crazy meter up to 11 that night. he will want to eat up all the scenery. he will try to establish himself at the alpha male in the room and swing it around in order to try to turn it into the donald trump show. which is more and more likely that this -- >> can't that represent the other candidates look good and distinguish themselves? >> yes. it can. look -- >> go ahead. >> there are four or five of these candidates in the top tier who are serious, smart people who are not trivial candidates. they are very well considered thoughtful people. they have all got policies. you may not agree with them.

bush rubio, perry, even rand paul, these guys come from different strains of the republican party. but they are all smart people. >> you don't win these debates -- >> donald trump is not a guy that you can compare them to. >> you don't win by talking about how rich you are and how smart you are. there are people on the stage that will be able to absolutely destroy him on foreign policy and domestic issues. so i think some of the candidates would relish that moment of really bringing him down. here is the other thing. donald trump is never in a situation that he is not in total control of. whether it be in his campaign stops, his tv shows, the reality stuff or his golf courses, it's always his environment you you are coming on his turf. he is not in charge on that stage. that's when you see him as the donald trump reality star not the real serious politician. i think that could be his

undoing. >> ben, then what are you hearing from -- you talked to the campaigns. what are you hearing? who do they think trump's end game is? you don't believe that he is in it for the long haul. >> ultimately, he is not spending money on ads or campaigns. he can do this as long as he wants to financially. as one campaign said today, look at how much money he has lost because of him being in this race. is he going to somehow stop this? is he going to go as long as he wants to? i think donald trump doesn't know what his end game is. it's going to be real hard for our campaigns to figure that out if the candidate himself doesn't know. the other thing is he isn't hiring political staff. he is hiring the same people that have been around him as a brand, as a reality star. from their perspective, i think they look at this as all press is good press. the more we get our guy on tv and the more people are talking about him, then ultimately that's good for us. if your game is to be famous if

success is just getting your name out there, he has been very successful over the last several weeks. i think he will go as long as he wants to. >> no matter what people say about he doesn't take it serious, it's a circus he is topping in polls. national and in iowa as well as in new hampshire. that means he is speaking to someone. what is the appeal? >> he is filling a void where all the other candidates are playing it very safe. it's very early in this presidential campaign. you don't want to go out there and throw massive punches. there's also a little bit of decorum here where the other candidates are saying get your campaigns going. we will see each other on debate stage. everyone is trying to raise their money. so they don't want to engage him in that way. donald trump is saying i'm the big guy in the room. you can start -- get too big too quickly. it's a long time until elections. he has peaked. >> that's an interesting point.

rick now you are back. >> i lost it again. >> we may have lost you once again. rick wilson, ben ferguson, thank you very much. we will see what happens with donald trump next week. coming up still to come new details about richard matt's final days including that brutal killer's last message to his daughter. corruption in prisons. correction officers working in tandem with dangerous prisoners. we have a special report for you. that's ahead. listen up... i'm reworking the menu. mayo, corn dogs... you are so out of here! ahh... the complete balanced nutrition of great tasting ensure. with nine grams of protein... and 26 vitamins and minerals. ensure. take life in.

tonight, convicted killer richard matt's final message. we're learning that just before matt escaped that maximum security prison he wrote a letter to his daughter. that letter postmarked just before the prison break, that's according to the "buffalo news." the message, he would soon pay his daughter a visit. we are learning that just before they escaped, there was an incident at the facility that prompted guards to ask for a full lock down a request that was denied.

how they pulled this off and more. >> caller: richard matt was so confident he would allude immediate capture after breaking out of his maximum security prison, he sent his daughter a letter. law enforcement sources telling "the buffalo news" matt wrote i promised i would see you on the outside. the daughter who lives in a suburb of buffalo, new york received the letter three days after her father's dramatic escape from clipnton correctional facility 350 miles across state. there's no indication she knew in advance of her father's plans. matt spent 20 days on the run before a border patrol special operations team found him alone behind a tree. he was shot three times in the head after aiming a shotgun at an officer. matt's body has been taken to the buffalo area after his family had a change of heart and decided to claim the body. the funeral home says there will

be no public or private services. david sweat is listed in fair condition. he continues to heal from two gun shot wounds he sustained during his capture. police put out a photo of the type of backpack he was carrying. they believe they took it from a camping ground and are asking the owner to come forward. possibly to trace the escapees route. >> what are they saying about this lockdown? what went down? >> it's interesting. a lot of people if they had done a lockdown they would have discovered this hole they made in the cell. i spoke to somebody from the department of corrections. they say, it didn't warrant that level of response. 30 inmates out of 2,700 were involved. there were no weapons. one person was injured. it lasted less than a minute. they didn't feel that locking the entire facility down would be justified. also you have to keep in mind

it's -- it wasn't just about this. maybe in behindhindsight they could have found the hole. they should have known about this. that's the issue. security has been tightened. they are doing random daily cell checks. but they are doing security inspections of the cells themselves. that's supposed to take place every week. it's all about the security. you better believe it's going to be tighter than it has been in the last couple years. >> it wasn't one missed opportunity to catch it. it was a whole string of them. great to see you. let's go through more details. joining me is a former sergeant at facility. worked there for 22 years. as well as a cnn law enforcement analyst and retoorired nypd law enforcement officer. let's talk about the mail. the mail isn't screens sscreened. why? >> the outgoing mail it's

private. there have been rulings in the courts from judges -- from federal judges that say we cannot open somebody's mail going out unless there's a problem with it. if there's a missed address, then we can check it out. if everything is legitimate we can't breach that privacy. mail coming into the facility, then we can open it up check for razor blades check for weapons, check for drugs. that we can. outgoing mail it's not -- we're not allowed to. >> quick on that though yes, hindsight is 20/20, the line we are learning when matt said i have always said i would see you on the outside, i'm a man of my word if they had screened it would this have raised a red flag do you think? >> absolutely. absolutely. as soon as somebody would have read that that he's going to meet somebody on the outside, a cell frisk would have been performed. we would have beenpaper in his

cell. >> let's talk about the other element about the prison riot one week before the escape. officers asked for a full lockdown. they got clearance for a partial lockdown. the important thing is, maybe if they had searched the cells, if they had -- because they got a partial, they didn't do a sweep of the inmates' cells. do you think that that is strange? >> well you know as far as i'm concerned, the bureaucrats never listen to the guides sguys on the ground. the officers asked for a full lockdown. they didn't get it. you know it's on the persons fault who stated there wouldn't be a full lockdown. they would have probably searched all of the cells and then maybe they would have found that hole in both their cells where they finally escaped from. >> what do you make of this? you worked there. as we discussed, this isn't just

one missed opportunity. there were many here to catch what these guys were doing. if they had done the full lockdown and sweeped the cells are you assured they had would have uncovered this in. >> absolutely. harry is on the money. the correction officers know what's going on in a facility. they know the gang relations that are happening, the atmosphere of the jail. when a fight like this breaks out and it's requested, it's for a good reason. typically at that facility in my career we have seen two or three lockdowns sometimes in one year period. that's just to go through, sweep the jail clean house, whatever we can find we can find. it also subdues the inmates in the atmosphere. we don't have any more problems between the gangs. it's a cooling off period. again, they don't want to listen. one of the other factors that comes into play that hasn't been out in the media is the fact that ramadan was starting. the muslim groups within the

facility that's one of the biggest gangs that we have going. that's state wide. if you upset the muslims, the department is very scared of that. they don't want to upset ramadan and the muslims. they try to -- they try not to have any lockdown during that. >> you suspect that could have been part of the motivation here? >> absolutely. they stopped the roadblocks. the roadblocks were taken in so they could have staff in the facility to start ramadan on time. >> i want to bring up one more thing. we learned that david sweat was in possession of a backpack. we have a picture of it. police put it out. it resembles this. police are putting out a call asking the public to identify who was the owner of this backpack. why is that important? david sweat has clearly been captured at this point. >> it's very important, because we will be able to track where he went and where he was at a specific time. if we find out from the owner of this backpack yesterday, this thing was missing tuesday from

one of my cabins or from my campground or something, we will know he was at that location at that specific time. that's why they're very important. >> interesting. that means they are still piecing together where they were when they were on the lamb. >> definitely. >> great to see you. thank you so much. coming up for us, richard matt and david sweat, they weren't the only killers to work the system. you wouldn't believe how some other notorious killers have gotten sex, drugs, money and others while behind bars. our special report is next. this is that rare occasion when a fisherman is happy the big one got away. he is my guest tonight. a new season brings a new look. a chance to try something different. this summer, challenge your preconceptions and experience a cadillac for yourself. ♪ ♪ take advantage

has worked the system for special treatment. from drugs to sex and more many of america's prisons are riddled with corruption. ryan young takes a look. >> reporter: richard matt and david sweat, their escape from a maximum security prison ending in a hail of bullets. matt shot to death and sweat was shot wounded and captures. authorities suspected the two had inside help. >> bringing them something from the outside. that's you where start breaking rules and that's where the system starts to fall down and break apart. >> reporter: investigators say for matt and sweat, help came from prison tailor joyce mitchell. they got close to mitchell to the point that matt had a sexual relationship with mitchell. a guard at the facility for more than 20 years. >> they manipulated edd a female to

get her to fall in love with them. they went that route, tried to make the friendship try to make the connection. see which one of these two, you know lit a spark with her to see what they could manipulate her for. see how far they could get her to go. >> reporter: the idea that inmates and prison workers can get close and make deals for contraband comes as no surprise to those who know how american prisons operate. eric was an inmate at clinton. >> you could pay officers off, number one. they looked -- they give you a blind eye. it's not even like they care sometimes. they want to get home make their money. they will sit with their feet up. you could walk around. on the visit floor, you can walk around with your family go to vending machines in some facilities. your family can bring it in in their underwear. >> reporter: even a notorious

tour as country music star battled alzheimers. every 67 seconds some one in the united states is diagnosed with the disease. what exactly happens to the brain as alzheimers progresses? here's dr. sanjay gupta. >> reporter: it only weighs 3 pounds texture like jelly and tons of wrinkles. yet that pint-sized prune of a brain is the most amazing powerful organ in your entire body when it is working right. when it is not, as in alzheimers disease, the results can be devastating. take a look here. the brain on left that's there mall. the one on the right, has advanced alzheimers. here is another view. see how the brain shrinks and fluid filled spaces expand. that's alzheimers crippling the ability to think and to plan.

and also look here at the hipocampus. it shrivels. the sea horse structure allows us to form new memories and the first to disintegrate. how does this all happen? it starts inside the wrinkled part of the brain the cortex where billions of brain cells interconnecting trillions of ways to create the nureuron forests. electric charges move signals like a baby's cry to the synapse. chemicals neurotransmitters leap across the gap, carrying the cry to more and more neurons and the memory is born. in alzheimers protein pieces called betaamaloid clump together and a protein, starts to fall apart, tau, create tangles that blocks signals and nutrients from getting through. cells begin to die. new memories cannot take ahold. the ability to think, plan deteriorates.

personality, behavior is affected. ultimately the once mighty brain is no more. >> thank you, sanjay. and "glen campbell i'll be me." this saturday night at 9:00. thank you for joining us. have a fantastic fourth of july weekend. a marathon of anthony bourdain, parts unknown, starts right now. ♪ ♪
