contributing factor to that. if you grew up consuming that and living that reality year after year and imbibing a paralyzing fear of police, and you chase that with a sense of total futility as each of these killings result in no explanation, no prosecution, cor the officer, no matter what the circumstances, when that is your every day it has to have an impact. it even covers the reporters. i know it has affected me. rachel will be back on monday. i will see you in the morning as we continue this conversation on my so "a.m. joy." >> thank you. this is msnbc's continuing coverage of the deadly attack in dallas 24 hours ago when what appears to have been a lone gunman shot and killed five and wounded seven police officers. two civilians also injured. here's what we know at this

hour. the shooter is dead after hours of attempting to negotiate with the shooter who the police had corn ired. police decided it was too dangerous to send officers up against him so they used a robot to detonate a bomb that killed him. he was identified as micah xavier johnson, a u.s. army reservist with no criminal record. officials stress the investigation into other possible suspects who may have assisted the shooter remains on going. >> i believe that i speak for every single american when i say that we are horrified. >> i've never been more proud of a police officer and being a part of this great, noble profession. >> this is a terrible blow to the city of dallas. it's a terrible blow to the united states of america. >> there is no possible justification for these kinds of attacks. >> we must learn to live together as brothers and sisters. if not, we will perish as fools. >> we are all outraged. >> we are better than this. >> we must stand in solidarity with law enforcement.

>> police across america feels this loss to their core. >> seeing the courage, the professionalism, their grit to stay on scene in an area, looking for suspects, knowing that we are vulnerable. >> today is a wrenching reminder of the sacrifices that they make for us. >> there will be a temptation to let our anger harden our divisions. let's defy those predictions. >> none of us can afford to be indifferent toward each other. not now, not ever. >> in a typical year in dallas, no police officers are killed in the line of duty, not one. and now after one horrible night, one man with a gun killed more police officers in dallas than were killed in any other city in the country last year. brent thompson loved his job and fell in love on his job. he got married two weeks ago to a fellow officer in the police

force of the dallas area rapid transit. assigned to be one of the peacekeepers because according to his boss, they needed, quote, someone with a personal touch and not a heavy-handed approach and brent was really good at that. he was a patrol officer, a great officer. this is very heartbreaking for us. we will definitely miss him. he was the first person killed in their history. brent thompson was a 1990 graduate about 70 miles south of dallas. brent thompson was 43 years old. patrick zamarripa, his mother said that patrick always had the dream that a lot of little boys have to grow up to be a police

officer. patrick never let go of that dream. before joining the dallas police department, he served in the navy and naval reserve and did three tours of duty in iraq and won several military medals. he was a sports fan beloved to his rangers and cowboys. today a friend said he's just a guy who wants to serve and protect during the day and watch a ball game with his family at night. patrick zamarripa was married with one child, a 2-year-old daughter. patrick zamarripa was 32 years old. michael krol was another one who was living his childen hood dream working as a police officer. he moved from michigan to join the dallas police force because that was the team to be on, a department with a good reputation. his uncle jim he wielke told us

he loved his work. quote, he was all in. he was all in. that's what his uncle said. his brother-in-law told "the washington post," quote, he was a big guy and had a big heart and he was a really caring person and wanted to help people. it doesn't seem real. his mom's had a difficult time. when his mother was reached by "the washington post" by phone she couldn't bring herself to talk about what happened to her son. after a few words she said, can we end this call? it's just a very difficult time. michael krol was 40 years old. lorne ahrens began his law enforcement career in california where he grew up before moving to dallas. at 6'5", 300 pounds no one was surprised to discover that lorne ahrens used to be a semipro football player. one officer told "the dallas morning news" he was always one of the happy ones with a smile

on his face. his wife is a detective in the dallas police department. they have two children, a 10-year-old girl and 8-year-old boy. lorne ahrens loved visiting his children's school in uniform to talk to their classes. and the kids loved seeing him. the school invite the him back several times. imagine the pride of that little girl and boy looking up at their dad in uniform in front of their classrooms. his wife, detective katrina ahrens told their children that he died doing what he loved to do trying to help people. the children's grandmother told "the dallas morning news" they don't get it. dallas police detective corporal lorne ahrens was 48. a cop's cop is the ultimate

compliment. sergeant michael smith received that from the dallas police foundation. he graduated from lamar university in 1989 and was an army ranger before joining the dallas pd 25 years ago. a friend told "the washington post" he was one of the good guys. the one you'd hope your kids would go to if they ran into trouble. michael smith's wife is a teacher. they have two daughters, 10 and 14. a neighbor said he was a very sweet family man always outside playing softball with his girls. a family friend said he loved his job and the guys on the force and he loved his wife and kids. sergeant michael smith was 55 years old. seven other police officers were wounded, three of their names have not been released. the four officers who we can

confirm injured. officer misty mcbride, 32 jesus retana, 39, officer omar cannon, 44 years old and officer gretchen rocha who has been released from the officer. two civilians were shot, one name has not been released. the other, shetamia taylor was shot when she was shielding her children from the gunfire. her sister will join us later in the program to tell us how she's doing. joining us now outside of baylor hospital is nbc news reporter tammy leitner. what can you tell us about the injured? >> lauren, still victims recovering and also there are a lot of police officers that have come to pay their respect throughout the entire day from the entire state of texas have come to visit their fellow

wounded officers. some of them were here overnight. an emotional moment when they all lined up outside of the er bay and two officers who had been killed came through and saluted them to pay their respects. we learned a little about the three officers with the dallas area rapid transit or d.a.r.t., omar cannon, misty mcbride and jesus retana. we just learned that jesus has been released from the officer and other two still here but expected to make a full recovery. we talked to an er doctor and nurse who were here and treated everybody and told us the doctor described the scene as just chaos. he said they had very little warning what was going to happen and didn't know how many more patients they were going to get. the nurse, we talked to her married to a police officer and she described the moment for me when she was treating these patients and she realized they were all police officers. she said it was just simply heartbreaking.

lawrence, back to you. >> tammy, what do we know about the extent of the injuries of the people who are still there and are -- any of them life-threatening? >> reporter: lawrence, very little information is coming out about the injured. they're actually making a point of telling us they're not going to tell us how severe the injuries are as a matter of respect and spoke with a spokesperson and possibly tomorrow they'll reveal a little bit more about their conditions. >> nbc's tammy leitner, appreciate it. joining us now a father and son earnest walker iii and earnest walker iv just a few feet away from one of the officers who was shot last night. earnest iii, let's start with you, tell us what you saw, where you were and what you saw. >> quewell, we had just completa

peaceful protest in which we had all races and all religious backgrounds and dispersing and the last thing the organizer said, hey, link up with somebody and go away safely. i believe that the shooters knew exactly where the parade was going to end and the next thing you know we heard pow, pow, pow, pow, boom, boom, boom, and it sounded like someone in a war zone. i was in the military and it sounded like these are some high-powered weapons. i immediately saw and i think that was officer thompson, i believe he was shot by a sniper, i'm just now connecting his name and saw him drop immediately in front of him. i was trying to film it and they were pushing us back. when he fell to the ground five officers immediately ran and threw their bodies on top of him and shielded him. when they rolled him over, his body seemed lifeless to me, i

was still recording at that time. then my second thought was where was my son? i lost my son and i'm looking for him and it was just chaos at that time. >> and let's hear from your young. young ernest, what was your experience of this? >> i was walking my dog like -- i was following the crowd. we were all doing -- having a great rally. it was peaceful and everyone was in unity. the officers working in tandem with rally -- with the rally supporters and my dog just right before we got to the end he just stopped about two streets over, just stopped and would not move, no matter how hard i tried to push or pull him, he wouldn't move and then once i convinced him to get up and walked towards my dad and go be with him at the front all i heard was shots going off, boom, boom, boom, boom, and my immediate thought was, oh, my gosh like i thought my dad had just been killed

because when you hear shots you don't know where they're coming from, what's happening and you immediately think that the people at the front are the ones that are immediately in danger and so all i could do was just turn around and run for my life and hope and pray that my dad was -- my dad was still alive and once i started hearing about what was -- these officers being shot, i mean, there's no reason for this. there was no reason for anybody to die. this is supposed to be a peaceful thing to bring us all closer, not divide us. >> how long did it take for you two to find each other? >> it took us about an hour. i got a cell phone call and i was line thank god. it was him and i answered immediately. i was at that point i was pinned down in a parking lot behind a vehicle right across from the parking garage in which i believe one of the snooims was located. and, you know, i just want to

say i'm sorry to all of these officers. if black lives really matter i want to make a challenge to black lives matters to put the names of these officers on your shirt along with the black men that have been slayed. because they lost their lives protecting black men. they were out there with no shields, they had no uniform -- they had no protection. they had no gear and the shooter waited until they had their guard down right when this thing was over and he's a coward and if black men did shoot these people it was an american soldier who was suffering for something. you got to take responsibility for that. he was in afghanistan, so we have to say that american soldier was domestic terrorism that shot this man. >> and ernest, i want you to go back to what you were just saying about you saw these officers protecting black people

since so many of the demonstrators were black people and talk about the way the officers reacted to the shooting as soon as they heard the shots what did you see officers doing? >> well, actually i believe one officer actually saved my life because when the shots rang out, their first response was telling people get down, get out the way, take cover. they were turning their backs towards the gunfire trying to make sure that citizens were okay because that's what they're here for to protect and serve. they didn't see color. all they were trying to do, hey, let's protect people then they started protecting one another. you saw dozens and dozens mobilize and they started focusing on el centro college and the parking garage and they were still trying to make sure that people were safe and people were down. >> let me talk to young ernest for a second. did you have any encounters directly with police officers during this, any communication

with police officers? >> i saw the entire city just sprung into action. every police car that they could find just was racing down the streets to get to the center where all this was going on and from hearing from stories of some people police officers pushed them out of the way of bullets. they even -- there were some officers that even blanketed some of the protesters to keep them out of harm's way so we were all -- this is just an alterable tragic event and just a shock to everybody that this happened. >> my son and i came up with a saying, back the blue but still remember the two because the reason was about those two young men who lost their lives senselessly and now dallas has another stain on its record. you know, we got through the jfk thing, it set us back. john hinckley jr. was from university park when he shot ronald reagan and now this,

dallas was moving towards a first class city and i believe this set us back quite a bit. >> before you go i wanted to ask you about you reported you believe it was officer thompson who you saw get shot. how long did it take to get an ambulance to him and to get him out of there after he was shot? >> they couldn't do it. i seen them once they shielded him they rolled him over and his arms were over his life and he was lifeless, he just dropped with his arms spread out and no ambulance could come in because there was still shooting. it was an active shooter. they just kept saying active shooter so you could not risk lives of emts to come in there to pull him out and that's the sad part about it that he had those guys could have pinned down. could have lived if they got medical attention a lot sooner. >> i'm very sorry for what you endured last night and what you have to witness.

ernest walker iii, ernest walker iv, really appreciate you both joining us. >> thank you and all lives matter. all lives. >> thank you. >> coming up next, one of the two civilians who was shot in dallas was shetamia taylor who attended last night's rally with her four sons. she used her body to shield her son from the gunfire and she was struck with the bullet. her sister will join us. that's next. >> i'm alex trebek. if you're age 50 to 85, i have an important message about security. write down the number on your screen, so you can call when i finish. the lock i want to talk to you about isn't the one on your door. this is a lock for your life insurance, a rate lock, that guarantees your rate can never go up at any time, for any reason.

i said several times today at some point i am going to cry

but not right now because we are too busy. >> shetamia taylor went to the demonstration with her four teenage sons. when the shooting started she threw herself on her son to protect her son from the bullets. she was shot once. she's in the hospital tonight recovering from the gunshot wound so now shetamia taylor has now given life to her son for his second time. joining us now is shetamia taylor's sister. can you tell me how your sister is doing tonight? >> she's doing well. she's resting comfortably. >> what about her are they with her in the hospital tonight? >> no, they are at home. they're exhausted. they were up here earlier with

her and they were all tired so they wanted to go home and rest. >> what happened last night, she was protecting one of her sons and then she was shot, so how was she taken to the hospital and did all of her sons go to the hospital with her last night? >> no. when the shots began, she got separated from three of them. it was a panic. when the shots began, she had eyes on two of them, her youngest and her oldest. it got a little bit behind her but she did see the oldest grabbed the youngest and run into the garage. that was nearby the location where they were. she lost sight of one of the middle age ones, the 14-year-old and the 15-year-old was by her side yell iing

out for her to see if she was okay. at that time, they heard the first bullet when they all scattered. the second bullet she pushed him down on the ground and between the two cars, and by the third and fourth bullet, when it started to going to be a lot of gunfire, she pushed him down and jump on top of him, it was going so fast and they were flying everywhere. she shielded him and somewhere in the midst she caught a bullet in the back of her leg. we know one -- my nephew that 14-year-old we lost sight of him for awhile so it ended up where we had to post on social media of a description of him because we wanted to look for him because we didn't know where he was. later on maybe -- go ahead. >> you know, you go ahead, teresa, go ahead. >> maybe i want to say 15 or 20 minutes in the oldest called to let us know where his location was and told us he was in the building with the youngest.

they were on lockdown. we couldn't get them. it took four or five hours until we could get them until everything began because they were on lockdown because they were closest to the location, and we could not get to them for four or five hours. we veal eventually found the middle age one who was taken to someone's apartment and he used someone's cell phone and at that time he snapchat to one of my nieces to let her know the location of where he was. andrew was in the police squad, the closest police squad to her. she was thrown in the back of the police squad, that was the closest to them to get her to the baylor hospital. >> when did you find out about this? >> i had just walked in from work, i want to say 6:30 that opening, yesterday evening and my mom immediately called

mean and she said shetamia had been shot. it took me probably less than 30 minutes to get down to baylor. as they brought her into the hospital, my oldest sister and i showed up at the hospital moments after they brought her into the emergency room. >> were you able to speak to her before she went in the emergency room? >> oh, yes. we walked right in the hospital and straight to where she was and we were in the room with her before they even splinted up her leg or washed the blood off of her. >> what did she say to you when she saw you? >> it wasn't what she said to us but what we said to her. why did you go to the rally? everyone wanted to go for the purpose of going to the rally but also the meaning of our minds -- it is no

good really can come from the event of a cop killing. we are from minnesota originally and we knew the events going on in minneapolis and we knew there couldn't be any good coming from at a rally where they say a cop killing a young african-american kid. so my thoughts were her to fuss. why were you down there with my nephews at this rally and you know it can possibly go wrong at some point. >> and what was her answer? >> all she can say to us was thank you, jesus, thank you jesus and i am just sorry for the cops that lost their lives. because at that time we were watching the news, we wanted to know the events going on as we were standing there and all she could say was thank you jesus and i am sorry for the cops that lost their lives and i am sorry -- i am happy it was not one of my kids, i am happy it was my leg and not my head. and those were her concerns. she wasn't even concerned as bad as she was injured because she

was injured pretty bad. >> teresa williams, thank you for joining us. we are glad that your sister survived this and her heroism with her son is amazing to her. i am so glad that all of your nephews are still with you. thank you for joining us. >> thank you. >> up next, investigators, what they are learning about the shooter. and we are continuing to monitor demonstrations around the country tonight. this is the scene in baton rouge, louisiana. we'll be right back.

we are continuing to monitor demonstrations around the country tonight. this is the scene live in atlanta at this hour. tonight authorities are working to uncover more details about the dallas shooter. nbc's jacob rascon has the very latest. >> reporter: lawrence, this is the neighborhood where the gunman grew up 20 minutes outside of downtown texas in mesquite, texas. an army reservist, somebody we know in the last few hours inside of his home bombmaking material, ammunition and a journal where he kept a record of his tactical

practices preparing possibly for this attack. they spent nearly three hours inside the gunman's home. dallas police detectives and atf agents emerging with large bags of evidence, inside bombmaking materials and vests and a journal of combat tactics. a neighbor who didn't want to tell us, micah johnson told us he didn't hide his arsenal. >> i know he's a part of a sergeant or something, i know he was a military or something. >> he worked as an aide for mentally challenged adults. he and his mother lived here for many years, neighbors say. all just 20 minutes from the ambush. he was an army reservist for six year, the recipient of various medals and ribbons. a neighbor says he would see him

practicing on obstacle courses armed with firearms and wearing his army uniform. this man coming out of the gunman's home did not want to answer questions. what was your reaction when you found out about this? >> excuse me, sir. >> tonight johnson's aunt telling nbc news that she believes bleepts shootings black men drove him to go on this rampage. outside of the home where the gunman live we have a patrol vehicle parked to make sure nobody knocks on the door because the family has grown tired of that as you might imagine and while the texas governor and the mayor of dallas and others have said that they believe and investigators believe that johnson was the lone gunman they want to be confident that there weren't any co-conspirators or anybody who possibly knew about the attack and that part of the investigation is ongoing. lawrence. >> nabs's jacob rascon, we'll be right back.

law enforcement telling nbc news the lone shooter who killed five dallas police officers used an sks rifle and handgun to carry out his deadly attack. the shooter was wearing body armor as he exchanged fire with at least 1 officers during the gun battle. some of it was captured on cell phone video. [ sirens ] [ gunshots ]

[ sirens ] joining us now eugene o'donnell professor of law and employs dud dis of john jay college and former police officer with the nypd, also joining us mark claxton the director of the black law enforcement alliance and retired nypd detective and joining us tremaine lee, msnbc national reporter. mark, you were with me last night as this story broke and guided us through so much of what we were seeing and i've been curious today as you've had some time to sleep on what we both experienced together here live as it was happening. your reaction to those videos now where we're hearing all of those shots and we now know what the representry was that was involved. what kind of tactical advantages you think do you think the shooter had last night? >> he had all the tactical advantages initially. he had the element of surprise

if you will. he had obvious opportunities for cover and concealment whereas you had these proud professional police officers in essence fully exposed. not expecting this to occur and it was quite traumatic and tell you the truth, lawrence, at several points once we had verification of some of the issues and some of the information coming out of dallas, it was difficult for me to watch and even maintain and offer some additional advice because, you know, quite frankly i had friends in the dallas police department so i was busy as we were going through everything trying to contact them to find out if they were all right or not so it's a very difficult time. it's a very painful time. it was a police officer's nightmare and i'm sure gene could tell you the same thing, it was absolutely a devastating police officer's nightmare and remains to be a traumatic event in the law enforcement community and across the nation.

>> eugene, it's such an amazing thing to watch because statistically as we know most police officers never face gunfire in the course of an 30-year career, never exposed to it and yet it's always possible and then last night that's not just exposure to a gunshot for a few gunshots, this is a barrage and they don't know where it's coming from and they're seeing fellow officers fall. >> right, i mean he brought a war to the streets of america and these are civilian police officers and the quandary. you want the cops to not be ready for war. they mostly don't want to be ready. at the same time they do think a lot of worst case scenario stuff and i'm sure mark could tell you a lot of types when cops get into situations it takes a while to process what's happening because even ordinary gun battles, they reckon at the end of encounters that the cops are just often caught off guard all together no matter how much you prepare for this and expect it when a live human pulls an

ordinary gun on you, it comes as a shock. when someone basically brings a war-like footing into the city of downtown very hard for the police to be ready for that. >> tremaine, we had a shooter here with seemingly an unlimited capacity for rapid-fire. >> that's right. you have to remember, this is kind of obvious guns are extremely effective at the only thing they've been created to do which is kill and even though we don't treat them as such in america, the killing tools, when you look what that shooter was able to do, one gunman able to inflict that kind of carnage and seen it time and again and orlando, the idea of close quarters with that weaponry and on the second floor of that parking garage firing down on officers, the carnage that we're talking about and the damage that those bullets do, again, these are actually killing machines. that's what they've been created

to do. no wonder. there's so many of them out there and have seen this time and again. yet we're not shocked anymore because this is what they do and it's the expectation. >> we've seen that in many ways now law enforcement is no longer a local activity and what i mean by that, mark, is something like this happens and every police officer and every dismrpt in this country wakes up this morning thinking about it. >> yeah, yeah, your heart drops, you really completely relate and you can -- if you've had similar experiences you understand that the emotional toll that it takes and then also consider this, this is what separates police from many other professions. if you can imagine what other profession can you -- is out there where you have an individual walking to a workplace, for example, and kill several people in that workplace. by the next day, of course,

everyone is traumatized. there would be professional counseling and there will be demand of our professional police officers, the next day you have to go in with your heavy heart and vulnerable feelings and perform the same job and perform it for longer periods of time. it's an expectation of excellence that you expect from your police officers, your professional police officers and that's what separates oftentimes the policing profession from any other profession, those police officers had to go in this morning and work extended hours and leave their families with this feeling of vulnerability and pain and anguish over the loss of their colleagues. >> eugene, the effects of police work have become nationalized too. 30 years ago chicago captain howard said a police officer can do something in a second or a minute that sours a community for a generation. well, now a local police officer

can do that and sour communities throughout the country instantaneously. we're having a nationwide reaction this week to what happened in baton rouge and what happened in minnesota. >> yeah, but i do think at the end of the day they're enormously reasonable and understand the job. it's the malicious stuff or things they think are overtly racist, not mistakes. just what mark said, the dramatic, law enforcement is a family and really significant ways when a child goes missing, when a senior citizen can't be located, when a death notification has to be made across the country, the new york city police department regularly reaches out in the smallest towns a young lady comes to college in new york, goes missing or is found dead, face-to-face notifications are the norm. we ask the smallest departments, t two-officer go to the door and

it's seamlessly, not about fugitive apprehensions but humanistic and it's about looking after people and while this is dramatic and heroic the law enforcement community comes together on much less dramatic but significant issues that are really about protecting people, looking after people. >> trymaine, talk about how the local reaction to controversial police activity becomes a national reaction. >> i think one thing that is so interesting about this nationalizing of what i would describe as a collective trauma, repeated exposure to extreme violence, city to city doesn't really change much whether somewhere in florida or in missouri, california or in new jersey, the sentiment is always the same. there is a heavy burden on folks who are living under such conditions, seeing loved ones shot and killed by people in the community or by the police. but especially when it comes to the state sanctioned kind of violence we've seen when police

officers are killed and in turn there is very little chance they'll be prosecuted effectively let alone charged or found guilty. this is how the large network of organizing has expanded because everyone has that feeling, i think the one part that we miss sometimes is the deep hurt, everyone focuses on the anger because we can see the anger, we can smell, taste and feel the anger but the hurt that people have manifests in so many different ways but when you talk to folks one directi-on-one or tuesday or wince, they'll tell you they're hurt. people are protesting all around the country right now because they're hurt for those families who lost loved ones. so many people complain when it's black on black crime no one is out there. people who say that simply aren't in the black community because there's hurt and pain and anguish every single day and so we talk -- when we talk about the big picture and see what's happening all across this country, many have said they're

surprised, unfortunately what happened the other night here, but they're surprised that it hasn't happened because there's so many young people in such deep anguish and so angry and they don't feel like they have the tools to express themselves and that's how this whole feeling has cast itself from city to city, state to state. >> trymaine lee and mark claxton, thanks for joining us again tonight and thank you for guiding us through our live coverage of this event last night. thank you, mark. >> thanks. >> we will continue to monitor demonstrations going on across the country tonight.

i appreciate you because at the end of the day what we have to do is do this the right way.

tlfrments has been a vicious and calculated attack on law enforcement. even as yesterday i spoke about our need to be concerned about racial disparities in our criminal justice system i also said yesterday that our police have an extraordinarily difficult job. we also know that when people are armed with deadly weapons it makes it more deadly and tragic. in days ahead, we have to consider those realities as well. joining us now is christina greer, author of "blackett ni

nicks: race immigration and the pursuit of the american dreams." professor, i want to get your reaction on president obama. he had to go to the microphone twice. 20 -- let's see about 28 hours ago, he went to the microphone to talk about what we'd seen in baton rouge and minnesota and those tragedies and he spoke extemporaneously, movingly and found himself going back to the mike tone to talk about the lives lost in dallas. >> right, so we have a few issues on the table right now, right, because how many times can president obama come to address the american public to talk about the crisis of guns and what we're doing with guns? that's one. number two, there is a real issue in this country about being a black american and dealing with the police state. it is clear, it has been happening for many generations, we just now all have cameras and

we can see it in realtime. that has to abe addressed. we're seeing people in the black community slowly realize it has been going on forever. both and we now have the tragedy in dallas which serves as obviously a wake-up call for the law enforcement community, it's tragic, it's horrible but we also have to remember the reason why people were gathered there in the first place which is to assert their humanity and their americanism to actually say please validate us. like we are actually living in a police state in our own communities so we have all these conflating issues going on at the same time. in the midst of a presidential campaign where obama in many ways is trying to step back, right, and let hillary clinton step up, but he has to still lead until mid-january and so these are issues that no one expected him to solve. if they did they were incorrect but we're now seeing his

presidency being confronted with race in the way he hasn't addressed in the past seven years. >> the campaigns and presidential campaigns basically suspended today issued short comments about it and will presumably have something more to say, i would expect, by next week. this is a tragedy that's going to be with us for awhile and see a series of police funerals and plenty of opportunity and demand one would think for political comment on this from the candidates. >> and i think that the voters should actually demand that president -- that hillary clinton and donald trump -- a freudian slip -- actually say something because i think there's a level of respect that goes along with suggestion pepping a campaign during this particular type of tragedy, however, when you're president you need to work through these things and juggle many things at once and so i think we need some clear and concise not just

feelings of sadness and, you know, we saw donald trump sort of give one of his i guess best speeches thus far, but what's the policy proposal? right? what is -- what's your idea with the nra and communities and training police, with sort of implicit bias training and all these other things. >> we have to leave it there. christina greer, thanks for joining us. we'll be right back. >> i'm alex trebek. if you're age 50 to 85, i have an important message
