dallas are gathering in klyde warren park, at a memorial to honor the police officers killed on thursday. tonight we have learned at least two of the officers have been released from the hospital. in washington, d.c., the fallen dallas officers honored at a vigil. demonstrations against police violence are continuing. like this nighttime march in atlanta, georgia. there's another one going on in indianapolis, indiana. and meanwhile, we're learning new details about the dallas shooter. micah xavier johnson. we get more now from nbc's gabe gutierrez. >> reporter: before he would slaughter five officers and wound seven others in what police say was a well-planned ambush, micah johnson was described as a lonee. his page reflected interest in the black power movement, investigators said he had grown upset at the black lives matter

group. >> there appears to have been one gunman with no known links to or inspiration from any international terrorist organization. >> reporter: also tonight, new details about his time as an army reservist. a military lawyer who says he represented johnson tells nbc news the army prematurely kicked johnson out of afghanistan after he was accused of sexual harassment by a female soldier. the lawyer said the accuser requested a protective order and that johnson get mental help. but military sources say despite the allegations, johnson was not convicted of any criminal offense and received an honorable discharge from the army in april of last year. his lawyer wasn't sure why. but said it could have happened because johnson's service contract expired. now investigators are piecing together johnson's digital trail after finding bomb-making materials, ballistic vests and a personal journal of combat tactics at the home he shared with his mother. authorities scoured the crime

scene where a peaceful protest turned into panic. >> i heard six shots. >> reporter: damon crenshaw credits officers with helping save his life. >> they're part of the city. nobody wants to see cops die. >> reporter: outside the police department -- >> it's tough anytime you lose someone. it's tough anytime someone is taken from you unexpectedly. >> reporter: -- a texas-sized tribute. >> we're all human here. i think people feel each other's pain. that's what makes you hopeful to move from senselessness, to absurdity, to something that has redemption and hope in it. >> that was nbc's gabe gutierrez reporting. on thursday night when the shooting began just a block from where i am, there was a rush to escape. our next guest became an unlikely heroine when she ran into a young boy who got separated from his family. his mother had been struck by gunfire. and she ordered her four sons to run for safety.

all four are safe and sound due in part to angie, who found one of the young boys, rushed him to safety then took to social media to let everyone know he was okay. the mom, the shooting victim, it still hospitalized recovering after surgery. angie wisener joins me now here. how are you doing? >> i'm fine. >> are you sleeping, eating? >> yes, ma'am, i am, i am. just kind of worried about the son. i still want to hear from the son to see how he's doing. >> let's talk about what happened that night. explain where you are, what you heard, and how you two came to find each other. >> we pretty much were in the protest on the last little stretch, leavingt courthouse. we tame to the brick building. we just heard a whole bunch of noise. and me, my cousin and my cousin's three kids were together. we took out running. as we were running, he ran up behind us. and he was like, ma'am, ma'am,

can i stay with y'all, because i lost my mom. i don't know where my mom is. i said, okay. >> what goes through your mind when a little kid comes up to you and says that? >> okay. like i have three kids of my own, two boys and one girl and a stepson. i'm like, i'm for the kids regardless. when he said, i didn't even think about it. i was like, okay, come on. yes, come on. we kept hearing gunshots. we were still trying to run together. he was like, let's go in the hotel. i was like, they're not going to let us go in there. after he said that, we heard more gunshots. we kept running. kept running. >> he must have been terrified. >> yes. >> and he's not with his mom or brothers. >> yes. he kept looking back. he kept looking back. i thought maybe he was looking to see if they were behind him. but nobody was back there. >> did you take him home? >> no, ma'am. i was like, let's try to make it

to my truck. he had lost his phone. and we used somebody's phone. but he couldn't get in touch with them. i thought maybe we make it to the truck. you can call. we was trying to go to my truck, and the police kept turning us away because they were still shooting. we were running, running, running. we ran past an apartment, the guy was like, bring the kids in. come inside my apartment. my girlfriend's apartment. so we went inside of there. and from there, i was trying to get -- reach out to his family. and he was trying to reach out. i had my family trying to reach out to his family. what he had to do is download an app. i guess he used it on his phone, downloaded it on his guy's phone and brought up the information he needed. his mom wouldn't answer the phone. nobody was reaching out to him. >> his mom was probably in surgery. >> we didn't know at the time. at the time we were trying to reach out for them, they were putting up missing ads on facebook for him. we didn't know this at the time.

we didn't even know that they were looking for him. i didn't find that out until friday when i went back and looked on facebook. >> so how did you finally connect him with his family members? >> he downloaded an app. he got in touch with his cousin. his cousin told him that his mom had been shot. and that's how -- the family came and picked him up. >> you have heard from his mom on facebook. >> yes. she just said that she would really like to meet me and give me a hug. i would like the same. >> you said you're concerned about the boy. >> yeah. because i want to know how he feels. because i was telling him, let's just hope and pray that she didn't get shot. and if she did get shot, maybe it's in the leg. come to find out it was in the leg. >> you were the first person that a lot of people who came out of hospital was a sister. she had shielded one of her sons. and then i guess they all got

separated. what was the reunion like when he saw his -- was it his cousin? >> what he did is he started walking toward the car and gave me a real big hug. he was like, thank you, i was like, you're welcome, and he just left. >> how are you and your kids doing? >> my little girl was fussing at me. she was mad at me. my boys were like -- >> why was she fussing at you? >> she was scared something happened to me while i was here. i was trying to let them know and make them understand it was important for me to be at the protest for them and their future. >> why was it important for you? >> knowledge. knowledge. to me it's not about a black and white thing. to me it's about knowledge. >> well, i'm telling you, that kid was lucky that he found you, angie weissner, and i'm sure it's going to be something when you meet his mom. >> right. >> i know you're looking forward to that. >> i am. >> thank you so much for what you did and thank you for taking the time to talk to us. >> you're welcome. >> really appreciate it. and joining me now, msnbc

national reporter, tremaine lee. he's at klyde warren park. a little rain hasn't kept folks from going out there. >> reporter: despite the rain, there are at least a couple hundred people out here arm in arm, some hugging, some praying. the church has this prayer group every month. once a month or so. but now it's with a little bit of a heavier heart. one of their members, michael smith, was a police officer killed by micah johnson. he was a 25-year veteran of the force, 55 years old. his wife was a schoolteacher. over the years, he's won many awards. also at this church he patrolled their day care area during sunday school. a beloved member of that church. someone took to the stage earlier and asked everyone to think about the moment they heard about the killing. and they prayed. one man even came up to me, prayed with me.

folks here are trying to find answers to why. why this kind of tragedy would strike not just this city, but so close to home. but it's not just here in this park. it's all across the city. i spent most of the day on the south side of dallas, the historic black community, the heart of the black community there. i went to a community event. i asked folks there how do you wrestle with this idea of supporting on one hand, you know, an end to violence, on the other hand wrestling with this great grief and how they make sense of it all. here's what one man had to say. >> what created micah johnson? >> america. the same person that created dylann roof. what's the difference? only one went up in a sanctuary of a church and took out nine people. >> reporter: you can see here

the mood is somber. you don't feel the weight of grief in folks. people are holding hands, praying for some sort of resolution. again, this is something they do every month. but this time it was special. they asked for folks from other churches, other communities, whoever wanted to come and find some peace, some moment of solace. here they're doing it in the rain. even as there are so many more questions than answers. people are wrestling with heady ideas of race and violence, the police as warriors, out against their communities or guardians of other communities. these are all heavy moments and heavy times and heavy topics. but folks here, they came to pray. chris? >> we've seen it so many times before, coming together does help. it gives people strength, makes them feel like they're part of a community again.

trymaine, thank you for joining us. two members of the community we were just talking about. thank you both for being with us. >> thank you for having us. >> thank you for having us. >> obvious questions. i wonder how your communities are doing. how are people holding up? >> well, it's a difficult time. dallas is resilient. we're very faithful people. we're very committed to believing in things getting better. while we're grieving, we're grieving not as if there's no hope. the fact that things will get better. and it's going to be -- it's going to be a long process. >> eric, what do you think? can you even sort of put into some sort of context what's happened to your city over the last 48 hours? >> the best i can put it is why. i say that, because for a while we have been a model for the nation in terms of community and

police relations. so the question is, why. why us. why now. we're not like most cities. we do have a past. but we've gotten better thanks to our police chief, chief brown, and his efforts to have programs like let's talk, where we take students, troubled students, or just students period, and have a connection, a real heart-to-heart talk with police in the community. and to understand that on the police side, we want to understand who you are, and from the community side, to understand who the police are. >> does it occur to either one of you when the protest was happening and people coming out, that it would be anything but people? >> no. as we've seen, and police were part of the planning, and it was an effort, we've seen pictures where police officers and some of the demonstrators were smiling together, and so we had no idea that anything was lurking in that type of way. >> what's next? how do you take this and move

forward as a community? >> we'll go back and review our standards and make sure that we did everything that we are supposed to do. and could have done. but this is not something -- again, this was a peaceful protests. we've had hundreds of peaceful protests, hundreds of protests where nothing happened. this was an act of an individual who set on doing one thing, and he managed to do that -- create destruction and chaos. but we're a city that's coming together, built on love, supporting each other. we want to let the officers know that we support them. not only as an officer, but as a community, a city. >> whoever i talk to, black or white, i only heard praise for the police chief and how he's brought community policing into your neighborhoods. so this is a city that is known for the progress that has been made. but personally, when you heard what happened in baton rouge, and when you what happened in

st. paul, what did you think? >> here we go again. we've had too many of these incidents that have occurred, that have gone unprosecuted. so, you know, here we go again. and what can we do to prevent another incident like this happening. dallas or anywhere else in the country. you know, what actions must be taken. what process needs to be changed in terms of these investigations. do we need independent investigators who can investigate these cases and come back with a finding that will provide justice for so many of these families who have lost their loved ones. >> what can we do? >> i think it starts with the training. again, piggybacking off councilman thomas. it does deal with training, independent investigators. the officers that are wrong --

don't get me wrong, there are 99% great cops out there. but there are some bad cops out there. and that's in any profession. those individuals that are not right should be prosecuted to the law, if they're not following the law, the standards they're set to follow. >> well, i know it's going to be a long road ahead. it always is when tragedy strikes in a city. but i've also seen how powerful love can be, and community can be. and we're seeing out at the park tonight people coming together. so thank you for taking the time to come out. and our sympathies are with your city. >> thank you for being here. >> thank you. >> thank you. those are the dallas city council members. we're continuing to watch the demonstrations around the country. tonight, let's take a look at the scene in st. paul where protesters have amassed on a highway. we'll be right back. you get use to pet odors in your car. you think it smells fine, but your passengers smell this. {ding} eliminate odors you've gone nose blind too,

for up to 30 days with the febreze car vent clip. wow, it smells good in here. so you and your passengers can breathe happy. like bundling home and auto coverage, which reduces redney. tape, which saves money. when they save, you save. that's home and auto insurance for the modern world. esurance, an allstate company. click or call. this clean was like - pow. everything well? it felt like i had just gone to the dentist. my teeth are glowing. they are so white. 6x cleaning*, 6x whiteningá in the certain spots that i get very sensitive... ...i really notice a difference. and at two weeks superior sensitivity relief to sensodyne i actually really like the two steps! step 1 cleans and relieves sensitivity, step 2 whitens. it's the whole package. no one's done this. crest - healthy, beautiful smiles for life.

and i'm just a guy who wantsants to sell him that truck.ck. so i used truecar. it told me what other people in the area paid for the truck i want. and because we're a truecar certified dealership, i already know the truck he wants. so we're on the same page before he even gets here. -it's fair. -and it's fast. look good? looks great. this is how car buying was always meant to be. this is truecar. ♪

we have been keeping our eye on that situation unfolding just a short time ago at the dallas police department headquarters. an unidentified person racing past police officers into a parking garage across from hq. joining me now from dpd headquarters is nbc news correspondent tammy leiner. how is the situation there now? >> reporter: it's changed a lot from when it started when they got a call of a suspicious person in a parking garage, about 100 yards east of me. it's actually behind the dallas police department. we learned that this parking garage is owned by ibm and leased to the police department. that's where they park all their squad cars, their personal vehicles, their undercover vehicles. and so there was a report that there was suspicious person in there. so police took up position around the parking garage. they eventually went through and searched it. they first used their armored vehicles and went in on foot and searched it, finally they sent in canine dogs.

and used the helicopter overhead. they cleared the three-story parking garage. they found nobody. but they did -- this took about an hour and a half for them to search it. it is clear now. things have resumed out here at the memorial. you can see that there's still a lot of people gathering out here, paying their respects. there have been people coming and going all afternoon. things started to die down a little bit in the afternoon when this situation was ongoing. but now it's picked back up. a lot of people just wanting to show their support, not only for the dallas police officers, but the dallas community. >> nbc's tammy leitner at the memorial. thank you, tammy, reporting from there throughout the situation as it unfolded. the events in dallas, of course, happening in the midst of a heated political campaign. neither donald trump nor hillary clinton were out on the campaign trail, although both have responded to the horrific events of this past week. in an online video, trump addressed the tragedy in dl las

as well as the deaths of sterling and castile. >> it's an attack on our country and our families. we must stand in solidarity with law enforcement, which we must remember is the force between civilization and total chaos. every american has the right to live in safety and peace. the deaths of alton sterling in louisiana, and castilo in minnesota, make clear how much more work we have to do to make every american feel that their safety is protected. >> speaking in philadelphia last night, hillary clinton emphasized the need for compassion and empathy following this week's events. >> there is too much violence, too much hate, too much senseless killing, too many people dead who shouldn't be.

we need to try as best we can to walk in one another's shoes, to imagine what it would feel like if people followed us around stores, or locked their car doors when we walked past. let's put ourselves in the shoes of police officers, kissing their kids and spouses good-bye every day, and heading off to a dangerous job we need them to do. >> joining me now, bloomberg political reporter who is covering the trump campaign. and daniel strauss from politico covering the hillary clinton campaign. thanks to both of you for being here. i have to say, kevin, a lot of people have been surprised by the relatively restraint we have seen over the past several days from donald trump. are you? >> well, chris, we did hear him in the statement you just played. not only reach out to the law enforcement community, which, of course, is something that he has

done for several months now into his campaign. but we also heard him allude to sterling and castile. that really did take some of his political critics by surprise. clearly this is part of a larger and more broader effort on the donald trump campaign's part to really shift tone from a primary election to a general election strategy. now, that being said, he did have a fund-raiser earlier today in the hamptons. he will be back on the campaign trail on monday with a scheduled event in virginia. but this is a donald trump who has struck a much more measured tone following the horrific tragedies that we've seen over the last week. >> on the other hand, daniel, i think a lot of what we've seen from hillary clinton is pretty much what you would expect to see from hillary clinton in a situation like this. >> it is. you know, for a long time she's actually been talking about criminal justice reform, changing in police practices, and really sort of addressing

shooting incidents like the three we've seen in past days and weeks. so it's not so surprising that she's taking a somber tone here. this really just falls in line with her previous reactions on horrific incidences like these. >> somebody who has faced it as a diplomat, and obviously as a senator. "washington examiner," phil kline said, i feel this tragedy has been less politicized than others. almost a collective despair on what's going on in the country. and when i read that, kevin, i thought one of the things about donald trump is he has been very good at reading moods, right? i think a lot of his initial success was, i watched him go into those rallies, and you could see him playing off what people were reacting to. do you think in addition to him wanting to take a more measured tone, certainly members of his family and staff want him to,

that he is reading the country? >> two points. the first is that we've seen this, as you said, after the terrorist attacks, after san bernardino shooting, we've seen donald trump really tap into the frustration. and candidly, the anger of the american people during that primary, where he did, of course, increase his lead. and now, you know, you said it again, i think there is a collective despair in the country when we come to these issues. the second point i would make, chris, is i've spoken with trump sources just this weekend, and within the african-american conservative leadership movement. and what they told me is that they were urging donald trump to, again, adopt that tone, to aagain highlight and reach out to the victims of some of these shootings. and he's done that. he has listened. so i think the question becomes, how do we move forward. you know, hillary clinton has spoken about this as has the democrats on capitol hill for quite some time. but there has been no deal.

there has been no action. donald trump, the crux of his campaign argument, is that he would be able to work with congress, and make a deal. whether or not the voters believe that, of course, remains to be seen. >> daniel, i guess the question really is, how will this play out going forward. i think the conventional wisdom was going into the campaign, that when there was a crisis in the country, it would play to hillary clinton's strengths, it would play to her experience, it would play to that measured nature of who she is. how does this sort of play out as we go forward in this campaign? >> i think it's something we'll hear about in debates and we'll hear policy rollouts from both the trump campaign and clinton campaign going forward. in terms of surprise over sort of politicizing this event, we saw not so long ago the sit-in on capitol hill, members of congress demanding new gun legislation. so if that couldn't create some new legislation, it's unlikely that any quick fix, any new speech by either campaign will

solve the problem here. but i think later on in the campaign, we're going to see acknowledgement of this as an ongoing problem in the u.s. >> daniel strauss, kevin cirilli, thanks to both of you. we'll have much more from dallas when we come back. we're continuing as well to monitoring demonstrations around the country. watching the scene in new york city's union square. we'll be right back. i asked my dentist if an electric toothbrush was going to clean better than a manual. he said sure...but don't get just any one. get one inspired by dentists, with a round brush head. go pro with oral-b. oral-b's rounded brush head cups your teeth to break up plaque and rotates to sweep it away. and oral-b delivers a clinically proven superior clean versus sonicare diamondclean. my mouth feels super clean! oral-b. know you're getting a superior clean. i'm never going back to a manual brush.

this is a city where emotions are running deep. and earlier today, i was at that memorial by police headquarters. a lot of people in tears. i saw texas attorney general ken paxton there, he came to pay his respects. and made time to talk with me about these tragic events and the effect they're having on his community and his own family. obviously the shooter is dead. where else do you see this investigation going? >> you know, i think the thing you want to make sure is he didn't conspire with anybody else. i know the dallas police department is looking into those details. i'm really proud of their work and what they've already accomplished.

in a really, really short period of time. it's not going to be one of those things that's done in 48 hours. >> does your gut tell you there will be prosecution? >> i don't know. i think that time will tell on that. how can we make sure this doesn't happen again. and i think the dallas police department has already been a part of that. they were protecting protesters that were protesting against them. and not only were they protecting them, they ran into the line of fire. that's an amazing story. run into the line of fire to protect people's free speech rights that disagree with you. i talked to my wife, i have three daughters at home right now, and this makes me appreciate being around them. and realizing that none of us are guaranteed another moment in life. we should all appreciate the time we have with our families because we never know when it's going to be over. >> are they okay? to they tell you they're scared? >> i think they realize this is a world where there's a lot of uncertainty. my daughter is about to head off to europe to study for a month

and a half. she goes off, and the last thing i told her is be safe. and she said, dad, you know i'll be safe. >> does it worry you? >> absolutely. you can't help when you see something like this, the randomness of it, really, for no purpose, this occurred, you always have concerns. especially about your children. >> that was texas attorney general ken paxton talking with me earlier today about crisis and the opportunities that come in the face of this week's brutal attack on the officers of the dallas police department. we want to continue that conversation. congresswoman eddie bernice johnson, and karen bass of california, secretary of the congressional black caucus. congresswoman, thank you for both being here. you and i were talking earlier today, and you heard him say, how do we make sure this doesn't happen again. is there an answer to that? >> there are probably a number of answers.

it's whether or not we can get to those answers. i think that if we could get some of these assault weapons off the street, i think we could get to the answer. we've been trying to get to that answer for a while, though. reauthorization of the assault weapon ban would be helpful. i think another thing that we need to understand is that though this happened in dallas, and we are in grief, this is a national problem. and we need to get assault weapons off the street wherever they are. we've had 491 murders of police in this country this year, as of june 30th. it is time for us to look at this seriously. and forget about the nra. i mean, it seems to me that we are tied in knots, because the national rifle association wants everyone to have a gun, i guess.

and there's nothing wrong with people having guns. i believe in the second amendment even though i disagree with the interpretation of it. i think it's meant for the militia. however, i support people having guns. but i think it's a sensible level that we should be dealing with, the number of guns that are on the streets, especially when we're not dealing with the mental health of people in this country. >> congresswoman bass, you know this well, because of what happened in san bernardino. it hit home in your state. and i wonder what you think comes next, and does what happened to two black men being shot, and what happened to five police officers being mowed down, seven more ended up in the hospital, does it change the conversation? what happens next? >> well, you know, i certainly agree with my colleague that we need to look at guns and we need

to pass legislation. i also think that one of the reasons why it's so devastating nationally when you have what happened to the two men is that time after time the shootings that the congresswoman referenced, there is almost never a conviction. how do you explain a 12-year-old who was shot after ten seconds when police officers saw him, how do you explain some of the shootings that have happened, and never a police officer ever being convicted? those are the things that lead to hopelessness. the other thing is, just the absolute denial, and looking at the individual that died and trying to expose their behavior or say there was something wrong. now the officer from minnesota is saying, well, i stopped him because he looked like somebody that was suspected of committing a crime. that's what's always said. so i think that we need to get over the denial and accept as a

nation that these incidents happen. you cannot always blame a victim. and that we need to look at retraining. we need to look at our police departments. and we need to say, actually, let's lift up the model of dallas. dallas was known for its community based policing, has been given high marks. we need to examine police departments where things are functioning well and figure out how to replicate that around the country. >> in the minute we have left, i want to ask both of you really where it goes. because we're in this hyper-charged political season. so many people's jobs are up. and you participated, congresswoman bass, in the sit-in to draw attention to gun violence. >> yes. >> and you heard republicans calling it a stunt. what do you do? if you feel as passionately as you do, and i know you do, congresswoman, what do you do? >> well, i think that we have to

continue the protest. we have to continue to make our voices heard. and really, i think when the public is so clear and rises up and says we're just not going to take it anymore, that's when you'll see change happen. congress has to act. there's just no excuse anymore. >> congresswoman, the emotion is running very high here. and understandably so. but how do you put that emotion into action? >> well, i hope we can continue to try to get the attention of the people that we need to bring about some action. we need the attention of the american people. but we certainly need the attention of our colleagues in congress. this is not a stunt. and we cannot stop. the pressure's too great. the need is too great. we must continue to call attention to the number of weapons, war weapons on the street, and we must change that. there's nothing else that we can

do but to continue. and we will continue. we'll continue because the people are demanding that we continue. >> congresswoman johnson, thank you for coming over on this saturday night. always good to see you congresswoman bass. secretary of the cbc who has been as an organization talking about these issues for a very long time. we'll have much more ahead from dallas. but up next, what we know about the dallas shooter, including his time in the military. we'll be right back. little miss muffet sat on a tuffet eating her curds and whey. along came a burglar who broke into her home and ransacked the place making off with several valuable tuffets. fortunately geico had recently helped her with homeowners insurance. she got full replacement on her tuffets. the burglar was later captured when he was spotted with whey on his face. call geico and see how much you could save on homeowners insurance.

're back live in dallas. gabe gutierrez reported at the top of this hour that there are new details out there of the military background of the man who shot and killed five police officers and wounded seven in dallas a few days ago. he was deployed to afghanistan, cut short after a female soldier accused him of sexual harassment, and requested he get mental help.

he was honorably discharged last year. joining us is msnbc military analyst jack jacobson. colonel, help us understand this first. how would a sexual harassment complaint like this typically be handled? >> there would be an investigation by the commander to determine whether or not the accusation had any merit. if it did have merit, then one of a number of things could happen. usually there will be some discipline. but if it were serious enough, it would be referred -- there would be an article 32 investigation, which is the military equivalent of the grand jury procedure. and it would be referred to a courts-martial. in a courts-martial, it could be a judge, if he were found guilty, he could be sent to jail for six months or even longer, in which case he would get a very bad discharge. >> now, we talked to the lawyer who was representing him in this case. and what he told us was that there had been conversations

about a plea deal. and under that plea deal, he would have gotten a general discharge. and in fact, he wasn't sure why he was honorably discharged. are you surprised that happened? >> yes, i'm shocked that it happened. and it indicates that maybe some malfeasance in the chain of command. whether there was a plea deal or not, this kind of behavior usually does not result in an honorable discharge, in which the recipient of the honorable discharge is then capable of getting all the benefits that accrue to people in uniform who have received an honorable discharge. now, he could have received a general discharge, or even a discharge under less than honorable conditions without getting a courts-martial. and then he would have reduced benefits when he got out of the service. but to let him get away with an honorable discharge indicates perhaps some malfeasance on the part of command.

it was interesting to look at his record and seeing, we were all surprised when we looked at the record and discovered in fact he only spent nine months overseas, was obviously let home early. when that happens, it's for some reason. it's shocking to discover that the reason was bad behavior, and that instead of there being something else, a judge, given an honorable discharge, i think there's some blame to go around. >> just really quickly, jack, if there had been a court-martial, would he have been able to get a gun? >> it depends. it depends on the state. usually what's required to prevent your ability to get a gun, in most states, is getting a dishonorable discharge, which can only be ajudged by a court-martial for a felony, and almost undoubtedly you would spend time in a military prison. for all other discharges, even discharge under less than

honorable conditions or a general discharge, in all the states i know, you can go out and get a gun. so getting a discharge, any discharge horne a dishonorable discharge would not have prevented him from going out and getting a gun. >> all of this among the questions that are being asked tonight here in dallas, and across the country. colonel jack jacobs, as always, thanks for being with us. >> you bet. >> we'll be right back. it felt like i had just gone to the dentist. my teeth are glowing. they are so white. 6x cleaning*, 6x whiteningá in the certain spots that i get very sensitive... ...i really notice a difference. and at two weeks superior sensitivity relief to sensodyne i actually really like the two steps! step 1 cleans and relieves sensitivity, step 2 whitens. it's the whole package. no one's done this. crest - healthy, beautiful smiles for life.

among the five police officers killed that horrible thursday night, is a 14-year veteran of the dallas police force. senior corporal lorne arens, married to a police detective and dad to 10-year-old daughter and 8-year-old son who will now have to grow up without him.

jaime castro called lorne his good friend. they trained together and i spoke with him earlier tonight. how did you hear about what had happened? apparently he had gone into surgery, was transported to the hospital. but after surgery, there was a complication. he went back in and apparently, the time his wife got there, he had passed. >> right. when i got to the hospital, i was there within minutes. and right away, i'm trying to figure out, obviously there was chaos. the hospital was preparing for more people to arrive. i'm looking for dpd officers, you know, d.a.r.t. officers were there already. and the few officers that i did find weren't sure what was going on. i'm not sure who it is, i'm not sure who it is. so i come around the corner and i see one of the commanding officers, and he had that look.

he knew lorne and i were really close and he had that look, and i was like who is it? and he grabbed me by the shoulder and he said it was lorne. you go through that state of no, it can't be him. i ran back to the front desk and said i need the name of the dpd officer right now. who is it? he grabbed me and said, hey, it's him. i said have you seen him? have you laid eyes on him to confirm it's him? jamie, it's him. and immediately you start praying in disbelief. and i wanted to be by his side. i said hey, i need to be there. i don't want my bud to be there alone. and obviously, you know, those are things that you just can't control. but it was tough. it was really tough. >> what you miss? >> him having my back. he was one of those guys just to

keep it short, the minute i knew he had -- he passed his training. so we're sitting in the bushes, believe it or not. we're conducting surveillance on these drug dealers and this is his first raid where he's going to be leading the charge, him and i and i tell him, you stick with me. you stick with me. stand behind me and i'm leading the charge. just stay by my side. and it's dark out there. and he kind of just taps me on the shoulder and goes, i got your back, brother. i'll take a bullet for you. and i knew at that moment, he had what it took to be a good officer. he understood the camaraderie. and i -- i knew he was part of the family at that point and understood what it took to be a good dallas police officer. >> we've heard all these stories about how the officers were

talking to the protesters and doing great community policing. and then running toward danger. would it surprise you that he was that guy? >> no doubt. no doubt. once i started seeing the videos, there was no doubt. i was like, there's no doubt lorne -- that's lorne and lorn e's leading the charge. there's no doubt. he had those officers' backs. he had the citizens. he's one of those guys that i don't care what beliefs he had, he was going to protect you and do everything he could to make sure you went home before he did. >> have you had a chance to talk to his wife? >> i have. and she's hanging in there. she's being strong for her kids. wonderful woman. i can't say -- i saw her grow through the department, as well. >> she is a detective. >> that's correct. wonderful, wonderful woman. wonderful mother. and she's holding on.

she's being strong. >> how do you go forward? how do you go to work? how do you face the day? >> it's tough. it's tough. i've lost other friends in the department. i was going on 19 years in the department. and you put that uniform on, and you can't help but to think of those officers, you know, you remember their legacies. and all you can do is honor them by getting out there and working. you keep doing what you love. and you do it to the best of your ability. and you serve and protect. >> what a tribute to his friend, my conversation with jaime castro. good friend of senior corporal lorne ahrens earlier this evening. the makeshift memorial in front of the dallas police department has been attracting a steady stream of people wanting to pay their respects. i visited the memorial today and spoke with some people there.

>> reporter: you seem quite emotion. >> well, yeah, it's tough on our club. we're law enforcement firefighter vets club and whenever officers are hurt, it hurts us. i mean, this is a senseless shooting, and i think that people need to realize that all lives matter. and these men and women that go out every day for us are the reason why we're safe today. and you know, seeing that, i don't feel so safe anymore. when the police are getting shot up, i mean this is crazy. i think everybody needs to come together as you know, citizens in this town. they need to all come together. i don't even know why when stuff happens in other towns and states that people would come down here and start -- start senseless shootings when there was nothing going on. this town has had great civil rights movements, and i think

this whole thing has kind of set it back a little bit. >> reporter: why did you want to come here today? >> because i had to pay my respects. it's just important that i think everybody should come out. if you love the police, if you love dallas, and if you're a good citizen, you should be here. >> reporter: what made you want to be here today? >> i don't really know. i just came. maybe some answers, maybe some closure, maybe some -- i don't know. i don't know what made me come. i just came. >> reporter: what goes through your head when something happens like what happened here? >> it needs to stop. it needs to stop. i mean, it's -- there's no words that can explain it. it's terrible. it needs to stop.

>> reporter: i just wonder why you came here today. >> well, i'm from anaheim. i'm here for a funeral, my godson and i wanted to come up here and pay my respects and see the community outreach. i can remember as a kid watching john kennedy get shot in dallas, a third grader. back again in dallas, the community is strong. they're going to get through this. wonderful people here. it was two black gentlemen who told me how to get there and said, hey, brothers we're going to get along. i said we are. >> you know, it never ceases to amaze me when i come to the scene of a mass shooting, seems like days ago that i was in orlando that there are so many wonderful people out there and how communities come together. i'm chris jansing in dallas. msnbc's coverage of the tragedy here will continue after this. many people clean their dentures
