good evening from dallas. i'm chris hayes and this is the continuing coverage of the tragedy in dallas on a friday night. right now, a mass of healing is about to shine. the mass is being led by bishop kevin ferrell. also at this hour we are watching demonstrations against police violence as we've seen in cities kraund the country. this is minnesota. of course, the site of the shooting of philando. and in baton rouge, this is where alton sterling was killed tuesday night.

that shooting captured on video. it was of course at the peaceful protest thursday night right here in dallas. a short way from where we are. a shooter won't a rampage, killing five individuals, wounding two civilians. we know at least two of the wounded officers have been released from the hospital and it has been an emotional day in dallas as residents have paid their respects of memorials. later tonight in washington there will be a vigil at the national law enforcement memorial to honor the fallen officers. also tonight we are learning new details about the shooter. nbc's gabe gutierrez is covering that. >> we're learning a little more about his history. while he was an army reservist. we spoke with a lawyer who said that he represented micah johnson. he says that he was accused of sexual harassment, johnson was, back in 2014, in april of 2014, while he was in afghanistan. he was prematurely sent home

from afghanistan because of these allegations. the military sources say that he was honorably discharged the following year. and that he was never convicted of any criminal offense. but in those documents pr those allegations, his accuser told him, or asked, she requested a protective order and she also wanted him to get mental help. so we're learning new details about the possibility that some of his history here, he served a tour of duty in afghanistan and right now, authorities are going through his digital trail. yesterday they found ballistic vests, as well as ammunition, and a journal. detailing combat tactics in the two-story home that he shares with his mother. >> the complainant in the case of the woman who sought a protective order, that was while they were both deployed? >> yes. she was a female soldier in

afghanistan. >> phrase was the thing that came out to me. that she wanted to get help for mental issues. >> we don't know any details. it was in the documents that the attorney read to us. we don't know anything further. we know again that he was not dishonorably discharged or anything like. that his attorney did tell us that he offered a plea deal to the army but nothing ever came of that. he says that it is possible he was discharged the following year because he was not sure. he said that's when his service contract may have expired. >> we've gotten some information about what was found in the search. we know there was a combat tactics journal. we know that, i heard bomb making materials. i think that's been confirmed. what do we know that the duration of time this was being plotted? it seems to me there was a pretty long tail on it. >> that's what investigators are looking at. neighbors do say that they saw him in a military uniform doing

what appeared to be tactical drills in his backyard. so, in the span of several months, the question investigators are looking at, what was the progression? did this somehow, was this something had that he had been planning a long time? and authorities haven't gotten into that so far. >> gabe gutierrez, thank you very much. all right. reaction to this tragedy has been pouring in from across the country. but especially if texas here itself. here is what governor greg abbott had to say yesterday evening. >> we as a people need to move forward and live our everyday lives. knowing that texas is going to be greater going forward, unaltered, unaffected by this act of cowardice. like this moment, we need replicate this on an ongoing basis. showing that we as a state of every people, of every color, every back ground.

that we unite behind the core principles that make the state of texas a truly exceptional state. >> joining us now, don't judge clay jenkins. i want to start out and ask how you're doing. >> i'm doing well. i was not one of the people out there risking their lives in the street that night. but they're doing well, too. and we're really feeling that support from the community. and that's helping a lot. >> i thought governor abbott's comments there, there's a key part. we've seen the ways in which mass atrocities, and we've had a number of them, can precipitate this panicked fear among people. they start on second-guess their ordinary routines. they start to move into kind of bunkers. and his call to not allow that to sort of take hold here in texas. >> absolutely. the shooter chose his course of action. now we get to choose our

response. we can't let his act of hate rip us further apart. we can use this as an opportunity on bring people closer together. what i've called on our community to do. if you're white, try imagine what it is like to teach your middle aged children, or your middle school aged children, a new set of rules, or a different set of rules than a white family or an asian america has to teach their children. if you're not a first responder family, think about that feeling of wondering if your loved one is coming home at night. if we begin to look at this through others' eyes, this is an opportunity to draw closer together and build a stronger dallas, a stronger country. we have to seize on that. we can't let this make us second-guess one another and second-guess the values that make us uniquely american. >> how would you describe this sort of political dynamics of dallas county? >> dallas county is a progressive blue county in a sea of red. it is a very diverse family.

45% hispanic, 25% african-american. it is very diverse. people get along well here statistically compared to other diverse urban areas. but there is still racial division in this county as everywhere in america. >> where do you see this going for this area? one of the things i've been thinking about, you have a chief of police here who personally has suffered through unspeakable tragedy in his own life. he is also the a package of reform that have been a model for many in the nation. he has faced tremendous criticism with the police union for doing so. where does this police department go? >> i think that we have an opportunity as a police department, as first responders near north texas, to take this as an opportunity to truly engage in innovative ways with the community. the community is very open and

appreciative of the sacrifice made by the officers. so to seize on that, to look at ways to communicate more effectively with the community, to look at our training to see if we can train officers on de-escalation as we look at new opportunities for conflict. if we can look at ways to reward officers for not arresting people but for diffusing the situation. there's a host of things we can do and now is the time to seize on those opportunities and do them. because i know that north texas loves these officers right now. and is backing them more than they had a long time. we can all feel it and it is appreciated. >> all right. judge clay jenkins, thank you very much. appreciate it. we want to show you the scene at the mass of healing in dallas led by bishop kevin farrell. let's listen in for a moment.

>> knbc got an exclusive interview with dallas mayor mike rawlings. >> other police officers the have died. having five at one time is heart-wrenching. but the connection with race makes it so challenging. we have to talk about race but we have to talk about it in a way that fills us up. that helps us get over this bridge. that's a tough one. >> joining us now, founder, one of the organizers of the dallas protest. good to have you here, reverend. >> nice to be here. >> how are you feeling?

>> you know, we've been protesting for some time in dallas and throughout the country. never in our wildest dreams did welling in our efforts to save lives would be this tragedy would come toward us. but we've been saying for years now, that the issues are issues in our country. and we've been asking people at the federal and state level and county and city to address these issues. so that these issues don't peak up to it. many people have different ways that they channel hurt and we know them. and until our government addresses these issues, the sad thing is we'll continue to have these issues and we need on address them. >> did friday night change anything? >> it didn't change anything because we've been talking about

these issues and saying that they will come if we don't address these issues. people are tired of officers being able to go away and get paid vacations when they shoot us down on the ground. you can see that through the actions of protesting throughout the country. enough is enough. we're tired of these issues being not addressed. >> it is interesting you say this. this mass is here in dallas. it was a peaceful march. it was in the wake of two shootings. this is been a lot of praise. what is your perspective? >> i wouldn't say that. people have been calling for his resignation for months. back in november we were told dallas police and the city of dallas was at its ten-year low. next few months later, dallas, the state troopers and the fbi

to come in. o officers are leaving. when it comes to community organizations, addressing police brutality, we're never brought to the table. girl scouts of america. boys and girls clubs are brought to the table. we're never brought to the table about the issues addressing police brutality in this community. so i would not say that. i would not say that i would stand up for our community in addressing these issues but i will be definitely prayerful because of the situation that he's going through right now in his department. but at the same time, we have been addressing this shoor for some time in dallas. and dallas has a fine way of covering up shootings. >> after what happened friday night, what do you say to someone, a police officer or a police officer family member who says, look.

if police officers act aggressively at times, or if they act jumpy or they jump to conclusions, this is the background context that is informing that. this thought that around any corner in america, there could be someone with a gun trying to kill them. >> regardless of the fact, police and law enforcement voluntary to risk their lives in america. and any kind of job you have, you know your responsibilities and the risks of every job. if this is the wrong career path for you, because the one thing that you do, you're commissioning to protect and serve the people. just like with lieutenant dan patrick said, when people were running back in. oh, they're a hypocrite because they wanted the police to protect them. what are you trying on establish here in texas?

or you are trying to militaryize our police? or to protect and serve the people? they can what they were supposed to do. and no one was hurt. >> you feel they protected and served friday night. >> they protected and serve. however, at the same time, what happened that night, no one, no one in our wildest dreams would have thought that happened. it is time for this community to have real dialogue and real actions from that dialogue. and bring the change that is needed. and not bringing out the local pastors, addressing the issues that don't be in the community. >> to be cheer, it sounds like you feel like the moment will be swept under the rug. >> as always. the people addressing the issue in dallas and all across the country, the activists are not listening. they bring the people in to represent the community that is

not representing the community that has the problems. >> all right. thank you very much for coming by today. really appreciate it. the president and founder of next generation action network. one of the organizers of the march in dallas. this week's tragic events unfolded as president obama had been scheduled for a trip to europe. he was there for a summit meeting with nato. president's strong reactions and his role during this extremely painful time are next. don't go anywhere. 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.

today, president obama continued his overseas trip to poland and spain, cut short by one day when returning to the united states tonight. and a wide ranging press conference in the polish capital, president obama spoke at length about shootings by police and in minnesota as well as the shootings police in dallas and said he was encouraged by america's reaction to the tragedy. >> we cannot let the actions of a few define all of us.

the demented individual who carried out the attacks in dallas, he's no more representative of african-americans than the shooter in charleston was representative of white americans. or the shooter in orlando or san bernardino were representative of muslim americans. they don't speak for us. that's not who we are. and one of the things that gives me hope this week is actually seeing how the overwhelming majority of americans have reacted with empathy and understanding. we've seen police continue to reach out to communities that they serve all across the country and show incredible professionalism as they're

protecting protesters. we've seen activists and grassroots groups who have expressed concern about police shootings, but are also adamant in their support of the dallas police department. and so as tough, as hard, as depressing as the loss of life was this week, we've got a foundation to build on. we just have to have confidence that we can build on those better angels of our nature. >> traveling with the president in warsaw today, ron? >> reporter: the president said it's a tough week. that's why he's going back to the white house and then to dallas next week. he tried to put the events in perspective for the american people saying that the people who carried out those attacks, for example, in dallas and in baton rouge and near minneapolis aren't representative of what

america is all about. this issue of policing and race has been a tough one for president obama throughout his time in office because he fundamentally believes there are biases in the criminal justice system but at the same time, said that's not an indictment of america's police officers. law enforcement has been critical of him for not always having their back. generally, he said race relations are not as bad as people will say they might be. he talked about how back in the '60s, there were police who were beating up peaceful protesters and that's not happening now. there were riots back then. he generally tried to keep moving the country forward through this difficult week saying that we have to just keep things in perspective and try to keep moving forward. he also raised the issue of guns, something he's going to face pushback on. guns he believes do contribute to the problem, do add to the carnage and said he'll continue talking about that issue. bottom line, the president heads back to the white house and then

heads to dallas next week and said he'll be meeting at the white house next week trying to ease some of the tension between some of america's police departments and the communities that they serve. chris? >> ron allen traveling with the president in warsaw, poland. thank you, ron. now, texas congressman, good to have you here. >> thank you, chris. >> we are not in your district. your district is in dallas. >> yes, nearby. >> what are you hearing from your constituents? >> people are sad. people are really confused about why this happened. all the constituents i serve have a great relationship with the police. they like the police. there are incidents from time to time that bother them but they have a great relationship with the police and it was very disturbing for them to see this. i know that for me being a north texan native.

i'm second generation ft. worth. i live maybe 30 minutes west of here at most and i know this is the saddest day that i can ever remember in north texas history. >> the president's remarks struck me as interesting because there has been so many times over the course of this presidency when things feel like they're spinning out of control or feels panicky and the president is steadfast. he's sort of being modulated and calm. he has a sort of optimism. do you see that as part of his role, rhetorically? >> his role is to calm the nation. make sure everyone knows we can work through this and if you look at some of the things he has done, particularly when it comes to trying to improve relations between the police and the community, he's done an outstanding job in that role and i'm glad that he's the president at this time. >> but what do you say to someone who said, how can you do

say he's done an outstanding role? we're two years past ferguson and look where we are. >> if you look at dallas, texas, for instance, despite the tragedy that happened here, which was terrible for those five law enforcement officials that lost their life, police chief david brown, he's put together some great community policing initiatives here. we've seen complaints lower by about 64% or so an a much more transparency under david brown and i think dallas has been a model in many ways around the country to really help improve communication between the black community, the latino community and the police departments. >> at the federal level, the president impanelled task force and will be meeting again. you're a member of congress. what can you do? what steps concretely can legislators take? >> i think we need a more robust

justice department as far as them and the community police initiatives they do. just west of fort worth, where i live, the fort worth police department is part of a six city initiative that the justice department is working on right now dealing with community policing. and i think we need more initiatives like that. of course, that costs money. the justice department can only do so much with the money they have. i think as members of congress, we need to appropriate more money to really do something about this. there's a lot of potential there and despite a lot of the negativity and conflict on television sometimes, regardless of where you stand on the issue, both sides want to see this come to an end as far as the tension between the police and the community. >> congressman marc veely, thank you so much. how the escalating use of military style weapons on police in dallas and other cities may

blur the line between warfare and law enforcement. stay with us.

a great example of a department that has taken the

police issue seriously and has engaged in an approach that has not only brought down their murder rates but also drastically reduced complaints around police misconduct. >> that was more of president obama's remarks from warsaw earlier today praising the dallas police department as a model of what 21st century policing should be. and in those remarks, he will reconvene the ferguson task force. more than a year since that group released their recommendations. joining me now, author of "rise of the warrior cop." reporter blogger at the "washington post" and nypd professor at criminal justice. i want to take this moment to praise your book, exceptional and changed my mind about some things and opened my eyes to a lot of things but that said, i

want to play devil's advocate and think he may want to chime in as well. when you look at what happened on friday night, one citizen that appears two firearms, and a military style assault weapon and a handgun, carrying out the level of mayhem, death, violence and destruction, how can you say to police departments, you need to dearm? you need to get rid of your vehicles and the robot when citizens can get access to arms that would make them essentially superior in weapons to the force that they are facing? >> well, look, i don't think anybody, even the harshest critics think that police shouldn't have s.w.a.t. teams or shouldn't have bulletproof vehicles.

the argument against militarization is not that the stuff shouldn't exist in police departments. it's that it should be used in the appropriate circumstances. it should be used when lives are at immediate risk. when you use violence to diffuse an already violent situation. most of the criticism is directed at the use of this kind of tactics to, for example, serve and some low level drug crimes and serve administrative warrants to do things like alcohol inspections or raid fraternities where they suspect underage drinking or where police suspect low level drug activity going on. so the idea that, you know, a city the size of dallas, i don't think anybody would argue they shouldn't have a s.w.a.t. team or this kind of gear. that said, this was a protest. a peaceful protest. the police officers were targeted because they were police officers and that would have happened. the killer could have chosen any

sort of public event. it's tragic. it's awful. particularly given that dallas was a forward thinking police department or still is, but what is the alternative? do we have cops, you know, showing up at peaceful protests in full riot gear where they sort of dehumanize themselves to the protesters and sort of create confrontation and violence from the outset? we do live in an open society that requires a little bit of risk both on our part and part of law enforcement. so, you know, it isn't about the possession of the gear itself but how it's used and the mindset that police departments and officers can sometimes get into when they use it and sort of being aware of that and guarding against it. >> i'm curious to hear your response to that. >> these are real issues and the problem with, or this dialogue, when you politicize this dialogue and front load this with answers that have to be the

answers and the libertarian argument is certainly that argument that no matter what, the libertarian formula is at the end, that's not a responsible way to do it. you can make interesting points. but to take it back to the other night, if you joined this coverage live, this was a city in terror. we didn't know who these people were or how many there were. the scope of this and the police were, as they always are in these situations, making it up as they go along. that's the nature of the work they do. and the nature of our country is that you have this extraordinary fire power available to anybody. it's not just about legitimate gun ownership but in our country uniquely in the western world, people can get these weapons and put a city under siege. what is more terrorististic than the police cannot protect themselves, therefore, they cannot protect you.

and these are real life issues. and made very good points and true points about the penny empty drug raids but can't have liberal, democratic, or ideological conversations that become just about scoring points and being a good debater. the cops actually protect these communities. >> but the question, to sort of respond using radly's point, i'll get your counter. part of the issue it seems to me, eugene, when you have a hammer, everything looks like a nail. what radley described is that departments get access to s.w.a.t. gear or surplus military gear and then there's a temptation inevitably to use that and you end up with no knock raids for a minor drug offense or administrative warrant. do you think that's a temptation for a department when it has access to certain kind of equipment to start using that equipment more than it would necessarily need to? >> absolutely.

it absolutely will. when this debate was going on a couple years ago, beyond this minor argument, that there was an implication that there was something sinister, that the cops were up to no good and snuck these weapons in, they had some conspiracy and that's what went on in the crazy parts of social media that we have to have a responsible conversation about this and not have that kind of hysteria but yes. we don't want to have the north of ireland or south africa where cops used to drive around in armored vehicles. that's the last thing we want. the irony here is that the police died probably, some of them, because they were not sufficiently protected by gear. but we have to have a balance and have a realistic conversation and these ideological debates are not helpful when you have to make real public policy. >> radley, we lost his satellite feed.

otherwise i would be getting his response. a fantastic book. well reported. and eugene o'donnell, former nypd officer, professor, thank you both for coming on the show. really appreciate it. we'll return to dallas in just a few minutes, but next, the latest political news concerning bernie sanders, hillary clinton, and their tug of war for the democratic party. stay with us.

today, democrats in orlando spent a second day working on the democratic party platform after allies at bernie sanders secured a victory by getting language to call for a raise of the federal minimum wage to $15 an hour and now the same suffered a defeat on the issue of trade. sanders allies hope to get strong language exposing the platform but were denied after establishment democrats overruled saying such language would embarrass president obama

and nbc political reporter alex seitz-wald. he's in orlando covering the platform. before we get there, just paint the scene of it. i was up very late and i couldn't believe, they were still voting at 1:00 or 2:00 a.m. central time. >> the gavel close at 1:41 a.m. last night. or i guess this morning really. it's a bit raucous in there. a lot of people from frustrated. it was a seven hour delay and a section in back for the public and bernie sanders supporters show up. they're booing, walking out, yelling shame. so all those delays are happening as negotiators work on stuff behind the scenes and this colorful scene in front of the cameras as well, chris. >> so what are the big takeaways in terms of what sanders folks have been successful and where they have not been successful?

>> i think sanders can feel good about what he's gotten so far. the big win is obviously minimum wage yesterday but just a few moments ago got a win on marijuana. that's creating a pathway to legalization. clinton has not supported that in the past. there's language on social security he wanted. wall street reform. breaking up big banks he wanted. and a ban of the death penalty, something that clinton has not personally come out against. and a bunch of smaller issues. some of which we haven't gotten to yet and a late night tonight on fracking and carbon tax but overall, sanders stayed in this race. a lot of people doubted whether he would have leverage after waiting so long, not endorsing hillary clinton but i think proved he did get some of his top priorities even though he failed to get tpp, his number one priority coming in. >> alex seitz-wald, thank you. joining me by phone, ben jealous.

i understand that alex just mentioned there's movement on some criminal justice planks in the platform. what's going on? >> hey, chris. you know, we've actually made a lot of progress. we had a moment where we had everybody up here including supporters, all voted unanimously to support a real police reform, language in our platform. you're talking about requiring doj investigations for every suspicious or questionable police killing. give the data collection we've been fighting for. the weapons of war out of our communities. and this is put by myself by

also waters and from the clinton campaign and like the victory on government wage presented by nick turner but henry of supporter of the clinton campaign. we've seen very big issues that representative sanders has been fighting for in both camps. coming together and support, really, have a great feeling of in contrast to the other moments we had this morning. >> it's interesting to hear you say that. i'm watching this footage. and striking to me. i was watching this play out with dispatches of how remarkably substantive this moment is. you have people in a room arguing it out about the basics of policy, the basics in granular terms of what age people might be able to buy into medicare. it seems a world away from a general election campaign thus far that have been fairly bereft

of that in general. >> we're seeing the process of creating consensus at the base of the party. marijuana decriminalization, frankly, a pathway to legalization is to important because the base of our party, it's very party. and the reality is a bunch of clinton supporters came over to join our folks who would have been associated with our campaign and pushing it through. and so our campaign created a synergy for the people into our party and we want to keep them in our party. and the way we keep them in the party is to listen to them. we respect them and make sure it reflects the ambitions for our country. >> ben jealous, former president of naacp live in orlando for the second day of the platform committee meeting there going into the morning.

thank you so much for taking the time. >> thank you, chris. >> we're joined by california congresswoman barbara lee. a hillary clinton supporter and a member of the platform drafting committee. could we start on tpp? here's how i see it. i think there is strong opposition to tpp among the base of the democratic party. i think there's strong opposition in both houses of congress and both bernie sanders and hillary clinton are on the record opposing it. is the only reason opposition to it is not in the platform because the president of the united states supports it and at the end of the day, he's the most powerful democrat? >> believe it or not, i haven't endorsed secretary of state clinton nor senator sanders. >> i'm sorry, i misspoke. >> i wanted to wait to help write the platform to come together so that i could help bring both the clinton and the

sanders people together on the very critical issues because as a progressive, a former co-chair of the progressive caucus, i want to see this platform move in the direction i think people in america can place and i'm proud of what secretary of state clinton and senator sanders has done. this process has been very conclusive and heard from a variety of people in constituencies and it's going to be, i believe, a very good platform for everyone to embrace and bring consensus between the candidates and the constituency. there have been differences on a variety of issues. of course, the majority of labor and secretary clinton agreed on a platform position on tpp. i personally am one in congress who opposes tpp and i'm working to whip against it and not bring it up for the lame duck session but there were many differences of opinion on how this should be

framed in the platform and so what was put into the platform was supported by senator clinton and the majority of labor but let me just say also, there are so many good provisions which your previous speaker laid out. when you talk about a platform that stays very clearly, abolish the death penalty, breaking up big banks, it's a platform that focuses on economic security and income inequality by the $15 minimum wage plank. we talk very clearly about education and making college affordable. community colleges and minority serving. and should have a right of reproductive services by the amendment so i'm very confident that we're going out of here with a platform that everyone can embrace and be able to move

forward and beat donald trump in november. >> thank you very much. >> thank you. there is much, much more ahead. we'll be right back.

last night, i had the opportunity to discuss this week's tragic events with homeland security, secretary jay johnson. asked him about the shootings that proceeded the attack today and their impact on police departments across the country. >> in terms of what's happening now in dallas, i think it's important for us to note just as the shooter last night is not representative of the movement to peaceably bring about change

with certain police practices, police officers who engage in excessive force are not at all representative of the broader police force that serves and protects us on a daily basis in this country that happens in communities large and small. police officers serve and protect the public. they are public safety officers sworn to possibly risk their lives at a moment's notice. so in a day like this, it's important not to paint with a broad brush those who seek change through peaceful means to direct violence and hatred towards police officers and it's important not to brand all police officers for the actions of a few. >> you head up a department somewhat controversially created in the wake of 9/11. part of your job and the

government along with, i would say the department of justice and the fbi to protect america from terrorism. there are many people who call after various mass shootings. i've been in charleston after dylan ruf and this term, what does it mean? was this an act of terrorism? >> there are many different definitions of terrorism. this was clearly an act of hate. we know that from the statements the individual made himself about the police, about white people. the investigation is still early it's less than 24 hours old. i think we want to know more about the affiliations he may have been in contact with and as noted earlier on the show, the individual does not appear to have links or affiliations with a foreign terrorist

associations, isil or al qaeda but still early in the investigation and i think we want to know more. federal, state, and local is trying to learn everything possible there is about this individual before we put that type of label on this act. that's not to say what happened last night in dallas is any less terrible than an act of terror but more to learn, i believe. >> i just mentioned having gone through the massacre in charleston by white supremacists and people who pledged allegiance to isis and last night by someone who wanted to kill police officers, white police officers. >> i've said this for some time now. the global terrorist threat we face is evolving to include terrorist inspired attacks.

those who self-radicalize and for their own reasons, commit mass violence. very often, the label we choose to put on something depends solely on the motive. though the actions could be the same, the weapons could be the same, the victims could be the same, and so in that respect, it's becoming more complicated to put labels on a lot of the mass violence that we see and it reflects the evolving nature of the threat we face here in the homeland. >> this gets precisely to my point about your job. you are tasked with preventing and the fbi and many parts of government to prevent attacks and how can you prevent a lone individual self-radicalizing along whichever ideology armed with a weapon perhaps legally

obtained from carrying something like this out? >> chris, it's a whole of government approach. when you conducted last interview, i saw one of our federal protective service vehicles. it's a whole of government approach. militarily, we take the fight to terrorist organizations overseas and we continue to do that. we take back territory. we are killing the leader of the islamic state. those focused on external attacks but it includes law enforcement effort, federal, state, and local. i also believe it's critical that public vigilance, public awareness is something that we continue at. public vigilance and public awareness can and has made a difference. it's important that we continue to build bridges to various communities across this country, not just the american muslim community but a number of communities where there's somebody in their midst who may

be turning towards violence. this is a whole of government effort and we keep at this but you're correct to know the situation and the environment has changed since the department of homeland security was created in 2003 and we are adjusting to it. >> that was secretary of homeland security. msnbc's continuing coverage of the shooting in dallas will continue. stay with us.

>> welcome back. i'm chris jansing. this is continuing coverage of the tragedy here in dallas. right now, dallas police have given the all clear after a tense situation at police head quarters that unfolded tonight. authorities on alert for more than an hour after reports of a suspicious person in their parking garage attached to the building. police moved the media away from the scene as they swept through the garage but after conducting a manual search, they've announced no suspects and no suspicious items have been found. also at this hour, people in dallas are gathering
