They are aware that the dallas gunman said that he was upset about the recent Police Shootings of black men. I think its very saddening and heartbreaking that Innocent Police lives were taken last night and we have to realize that just because we have innocent people in our community being killed due to Police Brutality doesnt mean we go out and retaliate against all other officers as well.

Muchneeded help in this effort. The same time, i offered him a flag of the state excuse me. The city and hell take that back and fly that in honor of this. Before we do that, though, i wanted to deliver a little bit of news that i thinks relevant that people want to hear. As many of you know, the Police Released the confirmation that the johnson, 25 years old, we have been working this case throughout the night and throughout the day and we believe that given the fact that we have today, that mr. Johnson, now deceased, was the lone shooter in this incident and by piecing together what was happening at the time, there was confusion by people running around but this was a mobile shooter that had written manifestos on how to shoot and move, shoot and move and he did that. He did his damage and we did damage to him as well. And we believe now that the is safe and that the suspect is dead and we can move on to healing. Part of that healing is to get the support all over the state and the Lieutenant Governor was here and now the governor of the state of texas. Thank you, governor abbott, for being here. Mayor, thank you. I want to thank you for the leadership that you always show but also especially the leadership that you provided over the last 24 hours. Youve been a voice of calm and reason that dallas is going back to work and also want for his unrelenting resolve for focusing on resolving this issue as swiftly as possible. I also want to express a gratitude to the state of texas for all of the First Responders who responded so effectively to the urgencies of last night and my gratitude to the white house because the of the president s trip we were unable to make an official connection but he wanted to express his sorrow and grief for the people in Law Enforcement in dallas but also any assistance that he could provide. Similarly, i want to thank my fellow governors. Ive had many contact me about ways in which they can help in dallas loss. This is a News Conference in dallas with the dallas mayor there. And he seemed to indicate that Micah Johnson was acting alone about written manifestos about shoot and move. In other words, taking shots and moving to a different location which is why we saw reports about multiple shooters. Indeed. We also heard from Texas Governor greg abbott thanking and expressing leadership in dallas as that city deals with this crisis. Yeah. This is reverberating all over the country, especially here in d. C. News4s shomari stone is with the protesters heading to the white house. Whats the mood out there .

Why police say he went around taking pictures of d. C. Landmarks. Two black men killed at the hands of officers and now five officers gunned down in dallas. Many folks asking how do we fix this problem . Coming officers say is working to do just that. And we know that Police Technology has come a long way since the wars in iraq and afghanistan started. Up next, bomb squad robots. The technology that officers use to stop the suspect last n even before the shooting in dallas, a lot of people had fears about the police and now some officers are also on guard. But there are a lot of departments like d. C. Where they are trying to improve that trust in the communities. News4s Meagan Fitzgerald has been speaking with officers and now shes live from northeast. What are they telling you about where we need to go from here . Reporter well, you know, chris, if you talk to a lot of people about why they fear police, many will tell you its because of the interaction that they had or an interaction that theyve seen someone else have. Thats why Law Enforcement departments like d. C. Police hold events like the one behind me here. Its police mixing with the community, a way of rebuilding trust andpe conversation further. Its a sad day for not only Law Enforcement but for the entire country. Reporter two black men were killed at the hands of officers, one caught on camera. I told him to get his hands up. Reporter the others livestreamed on facebook after shots were fired. Now the country mourns fivee [n Police Officers gunned down in dallas while protecting protesters. Its a dangerous job each and every day. Now theres a heightened level of fear. Reporter fear for officers concerned about being targets of violence. Were scared for our lives. Reporter and many people of color fearing those who are supposed to protect and fear their neighborhoods. Its a problem that retired pd dwyanest to be built. Beat the streets is a program npd has had in place for neerlg a decade. Neighbors enjoy food and games. Its very important to see that we can come together as a community and get things done. Everybodys job keeps people safe. It gives the kids an opportunity to have a fellow officer out here with them, you know, socializing and showing them we can all get together and have a nice time. It doesnt have to be a lot of violence. Reporter its something that many agree is a step in the right direction. You need more programs like that. That definitely cannot hurt. Will it fix the problem overnight . Absolutely not. But were heading in the right direction. Reporter now, this is one of just Many Community outreach events that npd has. This particular event, beat the streets, is in several different neighborhoods throughout the city at several different throughout the year. Back to you. Police used a robot armed with a bomb to kill the suspect which ended the hours long standoff. Tom, weve seen these robots before but weve never seen them used in quite this way. What did you learn about this . We dont believe that this has ever happened before. We think this is the first time that a bomb was ever used, detonated as an extension of a robot. We all know that robots have become very common with s. W. A. T. Teams around the country and taking the technology thats been deployed and used in these battlefield scenarios and then applying it to urban scenarios. This is the first time that we believe a bomb has ever been detonated and ive talked to a former s. W. A. T. Team commander who said, listen, i dont think they had any choice. They already had five cops down, were down and they could not get a clean shot at this guy. At a certain point, all bets are off, is what he was saying. If they were able to use modern tactics against the guy, by the way, armed with a semiautomatic weapon who was using battlefield tactics himself, that may be a watershed moment where Police Tactics are going in this country. This was a unique, almost unprecedented siege that we saw. A lot of people are concerned about how robots may be used in the future. I understand this probably would not be an option if you had a lot of civilians around. Could it change the way robots are used down the road . I think its likely to be studied by Police Departments nationwide. When they are concerned about putting their own people at risk in a scenario like that. That said, it is highly unlikely that were going to see police bombs but in extreme situations, the question is whether dallas has set a new standard or mark, i should say, in policing. And i think time will tell. It is also true that we are just a much more mill titarized soci and the police are outgunned. A sad turn of events. More coming up on nbc nightly news. Absolutely. Well take you to Montgomery Countys bomb squad and show you what their bombs look like. Tonight, a man from Northern Virginia is accused of taking pictures as part of a plan to help isis.

Now the 25yearold qamar faces the charges that he provided Material Support to isis. His parents invited me inside their home telling me that their son was arrested there earlier this morning. They didnt go to qamars hearing saying that hes on his own now. If hes responsible, let him suffer also. Reporter it was qamars twitter postings that drew attention to him. He set up 60 accounts with new we are jihadi pictures of beheadings. Qamar was befriended by a confidential informant who said that his cousin was an isis member. He confessed his murderous fantasies saying that he could slaughter someone if had the opportunity. The fbi had qamar under surveillance in early june as he drove with the confidential witness taking pictures of those sites. As he passed the pentagon, qamar shouted, byebye, d. C. , kill them all.

A Law Enforcement source tells me johnson was hit by gunfire before going into a Community College campus building that officers actually followed johnsons blood trail into the building. Police found him on the second oor and then fired more rounds through a wall. Apparently hitting johnson again and wounding him. After that, the negotiations with him began and after several hours, johnson threatening to charge the officers.
