Serve. We look at todays eyeopener, your world in 90 seconds. It is a sniper from up here somewhere. It is a sniper . You hear the shots. Get down. Get down. Target and Kill Five Police officers in dallas. Police say the snipers were targeting officers in an effort to injury and kill as many as they could. Get down officer down. Police started shooting in one direction, whoever was shooting, was shooting back. Thats when the war began. A peaceful protest. No one was acting up or crazy. Watch out we was running, they kept shooting. We dont know where it is coming from. I didnt see anybody else. It was just the cops. I believe i speak for every single american when i say that we are horrified over these events. Lets be clear. There is no possible justification for these kinds of attacks. You see video footage running towards gunfire, with no chance to protect themselves. To put themselves in harms way to make sure citizens can get to a place of security. All that to say the Police Officers put their lives on the line everyday is no hyperbole. We as a country, must come together, lock arms and feel the wounds that we all feel from time to time. And all that matters. If you take a stand for something, you automatically are against something else. It seems it is either antiblack or pro black and anticop. When in reality, you can be pro cop, and pro black. Which is what we should all be. On cbs this morning. Weve got tough history and we havent gotten through all of that history yet. We dont expect that in my lifetime, maybe not in my childrens lifetime, but all the vestages of that past have been cured. We can do better. People of good will can do better. Welcome to cbs this morning. Im jeff glor with christine johnson, and jim yuccas. We are learning more about a deadly attack on police in dallas. Snipers ambushed officers, turning a peaceful protest into chaos. Five officers were killed. Seven other officers and two civilians wounded. Video shows a gunman firing at targets at the end of the protest against Deadly Police shootings in other cities. Scott pelley is in dallas. He has been leading our coverage all morning long. He has new details on how the suspect was finally stopped. Scott. Reporter jeff, we heard from the dallas mayor and Dallas Police chief, david brown, earlier today. They told us that they were in a severalhours long standoff with one of the gunman in a parking garage just a couple of blocks from where im standing, where the Police Cordon is. Man told them during the standoff he was angry about the deaths of africanamerican men at the hands of white Police Officers over these last several days, months and even years. He said he was angry on behalf of the black lives matter movement. And as he broke off negotiations with the police, the police then decided to put a bomb on a robot, drive the robot over to the vicinity of the suspect, and detonate it. The suspect was killed. He had claimed he was acting alone, but the police are holding three other suspects, and manuel borakis has been covering this. Thats right, scott. This began with a protest march in solidarity. Two men killed, the one in louisiana and the other in minnesota. The Dallas Police department and Rapid Transit became the target of an enemy they could not see. The unprecedented assault unleashed dozens of rounds on Downtown Dallas. People marching at a rally stopped walking to run for their lives. The view from above shows how hundreds of people scattered. I was screaming, run, run, run, active shooter, active shooter. Reporter as the attack went on, several uniformed officers were down. Motionless on the pavement outside. Officers ran to the aid of their colleague who colleagues who were hit. One of the suspects, i a man with a rifle fired shots while hiding behind a pillar. We dont know where he is at. We got one more shooter out here. We got an open window on the side of lamar. Weve got rifles hanging out. All plain clothes officers need to be suited up in the area. Reporter two suspects was arrested in a traffic spot, one a woman who was caught in the garage. Another suspect inside the garage is dead. After a standoff. Mayor mike raulings. I would ask if youre at your home or at your office or at your school, to join us today in that spirit of prayer. To bring our city together and our country together. To heal wounds, not create them. Reporter the shooter who was involved in the standoff with police made a claim at one point that there could be explosives in the Downtown Dallas area, but scott, we know police have scoured the area with canines and havent found any. Manuel, thank you. It is also not clear how many gunmen there were. Manuel talked about the three people who were in custody. But the police have not said that they were directly involved in these shootings. Apparently, thats still under investigation. The man who was killed in the parking garage by police claim today have acted alone, but of course, the police are not taking that at face value. Earlier today, the Dallas Police chief, michael brown, had this to say about the suspect who was killed. Our Hostage Negotiator did an exceptional job getting this suspect to talk before he died during the hours of negotiating that eventually broke down. I want to share with you some of the comments from the suspect. The suspect said he was upset about black lives matter. He said he was upset about the recent Police Shootings. The suspect said he was upset at white people. The suspect stated he wanted to kill white people, especially white officers. The suspect stated he will eventually that well eventually find the ieds. The suspect stated he was not affiliated with any groups, and he stated that he did this alone. The suspect said other things that are part of this investigation, so that we can make sure that everyone associated with this tragic event is brought to justice. So as the mayor said, we wont expand on any further on what other suspects we have interviewed or looked at or their status, until we get further into this investigation and get closer to a conclusion of what and who are all involved. Reporter earlier, i spoke with john matthews, a former Dallas Police officer, and now executive director of the Community Safety institute. I asked him for his reaction to the suspects motives. Well, i think there are a lot of individuals upset about the Police Shootings that weve had, not only this week, but over the last couple of years throughout the country. But there is a way you can express your opinion about that. There is a way you can reach out to local Law Enforcement and build bridges. You dont arm yourself with weapons and attack and ambush officers during a peaceful demonstration. Reporter what should other Law Enforcement agency do to protect themselves now that weve apparently crossed this threshold . Well, weve been facing numerous ambushes over the last five years. Weve had officers in vegas sitting in a wrest rant. In new york city, shot in their own squad car. We have to practice significancenal awareness. We have to be on our toes at all times. We have to understand now that there may be people out there that are putting targets on our back, so not only do we to protect the citizens, weve got protect ourselves. There was a protest march, one among many across the country, there was one in chicago and a number of other cities protesting the shooting africanamerican men in other cities. What is the relationship between the Dallas Police department and the Minority Community here . Overall it is positive. I think for several decades, weve been building that partnership and trust. We meet with the members of the faith community, members of various communities throughout the city. We bring them in, talk to them about crime. We talk to them about social issues. We try to solve those problems for our citizens. Overall, we have a positive good working relationship, and our chief has set that tone for a number of years now. Reporter the mayor said that ironically, last year, dallas had fewer Police Shootings than any major city in america. It is good training, and bringing in tactics, such as deescalation techniques. Having the ability to deescalate the situation. So it doesnt get to a deadly force situation. There is no winners in that situation. You have the victims and officers traumatized for years. Usually the rest of their life. So we want to try to deescalate as well as we can. Reporter most of the seven wounded officers have been released from the hospital. Omar via franca is at baylor. Reporter good morning, scotts. The front page says it all. Ambush. The numbers have changed. 12 people shot five people dead. Five of them are officers. Making yesterdays attack the deadliest for Law Enforcement since 9 11. A gut wrenching tribute to dallas Police Officers as they saluted the bodies of the killed officers as they were transported. It is a hearbreaking morning to say that our Police Officers put their life on the line everyday is no hyperbole, ladies and gentlemen. It is a reality. Reporter the hail of gunfire from snipers ambushed officers who were securing the peaceful protest in Downtown Dallas. Several of the syringes were rush victims were transported. One of the dead, brent thompson, a seven year member of the force. He just realized that when she got shot richard mcbride, misty mcbride, was shot twice in the attack and recovering in the hospital. She was shot in the arm and broke her shoulder. She was shot in the abdomen, and it went in one side and just out the other side. A lot of gunshots. They just came so fast, and they wouldnt stop. Reporter Teresa Williams sister is one of two civilian victims. She was shot once in the leg after taking her four children to last nights protest. She immediately jumped on top of one of her boy, the 15yearold, she jumped on top to cover him. Reporter early this morning, mayor Mike Rowlings called for peace. We as a city, we as a country must come together, lock arms, and heal the wounds that we all feel from time to time. Reporter the mayor says he has received calls from the white house and Texas Governor greg abbott, offering condolences, but also help, because the Dallas Police department right now is just abut running on fumes, and their day is just going to get longer, scott. Because now they have the task of processing that massive crime scene downtown. Reporter omar, thank you. We have breaking news on this story. Cbs news has been told by a Law Enforcement source the identity of the gunman who was killed. He is identified as Micah Johnson. We dont have any more information than that about him at the moment. Were working to learn more about him now. Earlier this morning, we spoke with jeff hood, who was one of the organizers of the protest march, and we asked him what happened at the moment of the shooting. Where were you . I was at the very front. Because you know, as an organizer, i was trying to make sure that we were heading in the right direction, and that the, you know, the protest was heading in a peaceful direction. The protest was ending at that point. Absolutely. The march was ending. What did you see then . I saw right in front of me, i saw what appeared to be eight to ten shots. I saw two people drop, what i presume to be Police Officers. I was standing there talking to one of the police sergeants, and i turned and ran, started screaming, active shooter, run, active shooter, run, run, run. The violence in the country, you know, people dont engage those situations like it is actually a threat. It is almost like a lot of folks are used to hearing shooting in the neighborhood and that sort of thing. But once every figured out this was a big deal, people got to moving. Was there a lot of gunfire. Absolutely. I mean it, sounded like, you know, pop, pop, pop, pop, pop, pop, pop. I mean, just over and over. Did you see the gunman . I did not. You saw two Police Officers what looked like two Police Officers go down. Was there anything in the protest martha could have conceivable provoked this violence . No. No. Characterize for me the relationship between the 800 marchers and 100 Police Officers who were there. Sure. How was that relationship going through the march . Sure, you know, i think people were, you know, for a group of 800 people that were angry about the shootings in st. Paul and baton rouge, you know, i think it was a relatively calm environment. Even the police were commenting on, you know, just how nonviolent the scene was. And you know, for me, im just devastated that some things so beautiful could turn to evil so quickly. How would you characterize the relationship between the Dallas Police department and the Minority Community . I think it is typical. It is tenuous. No question about that. I think, you know, the police are trying to make it better, and i hope they continue. Why was it necessary to have this protest march . There were several yesterday around the country. Sure. Why was this one important to you . A lot of anger, and i think people need to have the opportunity to grieve and express their anger in a positive way. This was an opportunity to do that. For president obamas reaction, we will go to margaret brennan, who is traveling with the pressed to in warsaw, poland. Margaret. Reporter good morning.
