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.

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.

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.

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.
