In texas, learning more about the suspects in a terror attack near dallas. At least one linked himself to isis. Both were wearing body armor, and carrying automatic weapons. They got inside their target and wound add Security Guard before an offduty traffic officer shot and killed them. Tonight, many unanswered questions. Were also watching extremely tense situation on the streets of baltimore. Crowds gathered after police say a man dropped a handgun while being arrested, and if went off. It went off. Our correspondents are standing by. Our experts working sources to bring us the latebreaking information, and were standing by to speak with the attorney for the family of freddie gray. Lets begin with cnns brian todd hes in baltimore, and has the very latest. Brian . Reporter wolf the incident ramped up tensions because of everything that has happened here at the corner of pennsylvania and north avenues over the past week. The looting and violence of last week the protests that occurred, because of all of that. This incident that occurred a couple hours ago just ramped everything up more than it really normally would have. What we know happened. This occurred a couple hours ago. This information coming from lieutenant corner Melvin Russell of the Baltimore Police. There was an incident near this intersection of pennsylvania and north avenues. Police observed an adult black male walking armed with a handgun, saw him on closed circuit tv doing that. They moved to apprehend him. A short pursuit on foot ensued. At in point the mans gun fell and discharged. Its not clear if it fell as police were upon him or approach aring him, but at some point the mans gun fell and discharged. No injuries. The man was not injured according to police and he was fused medical treatment. Treatment. Police made him go with the ambulance out of an abundance of caution. Again, this man has no injuries. The gun went off. One round spent but according to police it did not hit them. The police according to the officer we spoke to Melvin Russell, never discharged their weapons. Again, this man is unhurt. Again, this incident if it had occurred maybe four five blocks away maybe at another time of day, another you know another location this would not have made much news. Because it happened here at this intersection it served to ramp up tensions a lot more. There was a Police Cordon across this street a short time after the incident wolf, but right now no visible Police Presence at this intersection and plings have calmed down significantly. They believe what the police say, brian . Accepting what the Police Version of what happened is . Reporter youre hearing different versions of that, wolf. Some are accepting it and some are questioning it. But no one is getting overly upset about it. Theyre going about their business, traffic is moving normally. And you know were going to wait and see if anything occurs. Right now the situation is calm and the police have moved out of the intersection. Brian, thank you. This afternoon the incident interrupted what baltimore hoped would be a return to normal after weeks of trouble and demonstrations after a busy but peaceful weekend, baltimores curfew lifted. National guard troops preparing to pull out and stores reopening. Our just it reporter evan perez has been talking with his police sources. Hes joining u. S. For more on whats going on in baltimore. Evan, what are you learning . Reporter wolf you know one of the things they know they have is a problem with the community and the trust that they thashs is lacking, frankly, and this incident underscores that, and theres a lot of work they need to do, they know. Theyre working on trying to provide some information to the public about steps theyre going to take to try to reform the Police Department. We expect that thats going to be announced in the next couple of days. But as brian said you know this incident quickly, quickly built. Theres a crowd that built up at the scene simply because people dont trust the police and people dont trust anything that they say, it appears, and initially the police themselves were very confused, because they were pursuing the suspect. They saw him on the crime camera what they call crime cameras, and thats why they tried to arrest him. They saw he had a handgun a revolver and apparently according to them the account we heard from them he apparently tried to toss the handgun and thats when the gun went off. And you know they didnt fire any any shots, but it was something that quickly they had to bring in riot police to make sure that the crowd did not go out of control. Wolf . Evan how were police positioning themselves with no curfew for 10 00 p. M. Tonight . Well you know theyve pulled back in a lot of the locations. We still see them downtown near the tour of the attractions that are the lifeblood of the economy here wolf but theres a lot less Police Presence here at city hall. Youre free to walk into city hall without having to show your identification. Thats a big change from the last week. But other than right there at penn north, which is the neighborhood where this incident happened today, you see a lot less visible Police Presence on the streets, wolf. Evan. Thank you. Well stay in touch. Joining us now in the situation room is billy murphy an attorney for the family of freddie gray. The man who was fatally injured while in custody of Baltimore Police. Billy, thanks very much for joining us. We saw an Immediate Response after a suspects gun went off on the streets today. Youve been listening to all of those reports. Certainly crime has spiked since tensions erupted in baltimore after freddie grays death bp there have been at least eight homicides since last tuesday, this according to the baltimore sun. How worried are you that the city is sort of still in a tinderbox waiting for something to happen . Im not worried at all, wolf. This is a great city. And everybody is anxious to get things back to normal. The Business Community is anxious to get back to normal. The people of the neighborhoods are anxious to get back to normal. Working people are anxious to get it back to normal and thats the spirit of the city right now as i gauge it and it is particularly impressive that the police appear to have shown tremendous restraint in this latest incident and that should be communicated, if the facts of it can be verified as quickly as possible because people need to know that theres been change, and this may be the harbinger. As you know immediately after this incident there were a bunch of people out in the streets who claimed that the police shot this young man. They didnt want to believe what the police were having to say. I guess the bottom line question is how much distrust is there in baltimore between young people especially out in the streets and police . Theres a tremendous amount of distrust. Theres a tremendous amount of distrust among the adults in baltimore about what the police will or will not do. And so as quickly as you can verify that this was an incident that was settled without injury and peacefully the more helpful that reporting will be and i dont think any of us need to speculate about it until it can be verified. That would not be a service to the community. You accept the version that the police have now publicly put out . No. Im saying just the contrary. Im saying, lets verify it. If the police are correct, get it out there as quickly as possible so people can understand theres a new day and that the police are showing restraint even under these kinds of circumstance. That would be great flus for baltimore. Certainly would be. It has to be verified w0678. Youre in close touch, obviously, you represent freddie grays family. How are they doing . They are not doing well. They have had moments of real uplifting. For example, when the Community Rallied behind them and continues to rally behind them. But theyre grieving. Theyre in shock. You can only imagine what its like to lose a child, or to be a sibling and lose a brother. So are they are they, though reassured from their perspective, that justice might be served . We hope justice will be served promptly. And there are two kinds of justice. Justice for them and justice concerning the larger issue of these Police Officers. So we hope that this thing can be re10678ed quickly, so that they can go about their life and they can grieve. Hopefully privately. Billy, if you can, id like you to stand by.

Breaking now new tensions in baltimore after police approached a man carrying a gun. Officers say the mans gun fell, discharged. No one was hurt. Crowds gather, though, during the confusion. Police came out in force, but things are calm right now. Were talking with an attorney for the family of freddie gray. There you see him. Freddie gray of course the man whose fatal injury while in Police Custody sparked weeks of disturbances. Well speak with billy murphy in a moment before we resooumt our conversation whip him i want to go to brian todd for more now on the secondguessing under way, that those Six Police Officers who face charges of what happened to freddie gray that it could be a very, very difficult case. What are you hearing over there, brian . Reporter certainly could be difficult, wolf. You know these streets, youve seen this afternoon, pulsating still with tension, with a lot of information. Of energy. A dramatic friday that touched off street celebrations, rallies, protests. Now the hard work of trying to get convictions begins for the prosecutions. Legal analysts say by no mean is it a sure thing. The prosecutor sounded extremely confident dropping the bombshell. Freddie grays death, Marilyn Mosby declared was a homicide. Now the work of trying to get convictions begins and mosbys cases against the six officers are by no means slam dunks. These charges are very tricky to get convictions on especially with this sets of facts. Reporter one of two former baltimore prosecutors we spoke to who says the second depraved heart murder trial will be especially difficult to prove. Typically its described in law schools across country, somebody who would throw a flower pot out of a 20th story window on a crowded street. A reasonable person should know thats going to cause risk to injure somebody or kill them. Reporter proving goodson knew beforehand he was creating a specific risk of death for freddie gray will be tough. An 4ri69 analysts say many cases against police are hard to win. Four officers acquitted in the rodney king case even though they were taped beating him. Also in the 1999 death of this man, shot him 14 times mistakenly thinking he had a gun. Often sympathetic to Police Officers because of the dangerous nature of their work. Im sure its coming. Try to get a change of venue in the case because juries tend to be antipolice to some extent in baltimore. Reporter lack of video in the police van are big hurdles in the gray case. Strong suit against the officers. The officers states attorney will emphasize innumerable requests mr. Gray made seeking medical treatment. Seems theyre banking on the idea mr. Gray petitions for herp and was denied. Reporter much will depend on the woman brings this case. Marilyn mosbys been the chief prosecutor in baltimore only four months. Only a few Years Experience as a trial prosecutor. She did have felony experience but didnt handle any homicide or wiretapping cases, or any attempted murders. The question then becomes, can a states attorney who did not have has experience handle a case of this magnitude . Are you trying to tell me what to do . Reporter could mosbys office get one of these officers or more than one to flip and testify against the others . The local attorneys we spoke to say that could be possible and if it did happen it would increase the chances of conviction but they say so far its not likely. They say the police have been supportive of one another, have a long standing code of honor and one, a former prosecutor finger on the pulse of the situation says so far the attorneys for the six officers have been working together. Of course, that could change. Wolf . Brian, thank you. Back with us is billy murphy. Hes the attorney for the family of freddie gray. How difficult of a prosecution, billy, youre an experienced lawyer in baltimore, how difficult will this be for the states attorney . Well depends on the rest of the evidence that she has. Nobody in her position would disclose all of the pieces to the puzzle. She was only disclosed what she thinks she needs to show probable cause. So we cant speculate based on what she has disclosed, how strong or how weak her case is going to be. There is a lot of time between now and the presentation of the evidence to a jury, and many things can happen. As one of the defense lawyers pointed out, somebody could roll on the rest of the Police Officers. And this code that they talk about of honor is not a code of honor at all. It is a requirement to be popular and accepted in the Police Departments of america that you not tell on a Police Officer if you are a fellow officer, even if the Police Officer violated the law. That is not a code of honor. And so if somebody comes to their senses and say, for example, i saw or heard what happened, this is what happened and if it incriminates a fellow officer, i would not be at all surprised if that socalled code of honor, which is really a code of dishonor crumbles. What do you make of we just heard from only on the job four moss never really prosecutored a homicide. Only 35 years old, relatively inexperienced. How much of a problem potentially is that . You know the assumption in that question is that she is going to personally try this case. Maybe she will. Maybe she wont. And another assumption is that she would try it by herself without the more experienced prosecutors in her office. Maybe she will. Maybe she wont. But lets look at whats most likely to happen. She has an extraordinarily experienced team of prosecutors who have been also assisting in the investigation of this case. It is those people that the defense should be worried about, not Marilyn Mosby. When i say that you put your best people on the job, and this isnt a question of her ego politically or otherwise. Thats what i think shes going to do. And so this question is really misplaced, because the assumptions are iran sincorrect, that the outcome or skill and experience that will come out in a courtroom is based on her and her alone. Will the gray family and you represent them also simultaneously or later file a civil lawsuit against the officers against the city, for freddie grays death . Thats a question that we havent answered yet. Were after justice. And so we want to see at much of the evidence as possible before we do anything like that, wolf. This isnt about a rush on the grays familys part to do anything in this case. We have the luxury of being able to wait until all of the facts develop before we do anything and thats what weve chosen to do so far. One final question before i let you go. A change of venue. You can assume the lawyers for the Six Police Officers theyll seek a change of are venue arguing they cant get at fair trial in the city of baltimore. How difficult will that be for those lawyers . And i ask you as an experienced attorney in balti
