A bang and just run for me life and a balloon . Staff. Just started running. How did you manage to get out . Told us to be calm and then a few minutes later let us out. Then ambulances came and the department of Homeland Security says there are no Credible Threats to music venues here in the United States. As the blast marks the Second Attack in the uk in just the last two months. Lets bring in Law Enforcement analyst jim cavanaugh. Heart breaking story. Where does the investigation go from here . They are focusing on the bomber, gigi, its in full swing now. Uk police said they have over 400 officers on this and they are going to be very aggressive. Likely they are conducting a search, a search warrant over there they quacall it a queens writ to go in the house of the bomber and get everything out, bomb making materials if there. Try to walk this back, see who he is and what hes about, wa exactly the motive is. And if it turns out to be terror then who are his accomplices or people who supported him or delivered him there or made a bomb for him. A lot of answers yet that were going to have to get unfolding in the hours ahead. There are investigators could know the identity of this attacker but are not releasing it when it comes to this investigation. You always talk about timing and target when it comes to these attacks. What does it tell you that this happened outside the actual arena in the ticket area or the foyer area, and it happened after the concert after people were exiting . Yeah, great point, frances. It tells you the real motive of the bombing which is homicide. You know we talk so much about suicide bomber but the motive here is homicide. Multiple homicide, mass murder. Thats the motive. Mass murder. You die committing the mass murder, thats the suicide. So, if it was just a suicide you would be alone somewhere in the park. But thats not what youre doing here. The timing is so critical. You are waiting for the crowd to come out. Now, you want to kill all the concertgoer. We dont know the reason he wants to do that, is it tied to international terror, maybe. Is it some other distorted plot in someones head. You know, emotionally disturbed person who wants revenge on whoever you know, Ariana Grande fans, we dont know that yet. Its more likely terror because thats the behavior weve seen over the years and certainly in recent years in europe at these big venues. That would be the major category but we dont know all of the answers yet. The terrorists centers are all spun up over washington, all over the world look at this real hard. Those analysts looking at us talk, looking at all of their threads, they are talking back to informants looking for the data on the bomb, data on the bomber. They want to see if they can piece anything together that might stop the next attack. Police are urging the public to share images from the scene. How critical is this to the investigation . Oh, its critical, really critical because you can with the closed circuit tv and the you know, Electronic Devices people use at these you can piece together the movements of the bomber just before the blast. And thats really important. He could be with an accomplice, remember the Boston Marathon bombers, the video showing them together, then separating to plant their bombs so it could be critical. Somebody could deliver the bomber there, walk up with him, hand him something. Give him instructions. He could be talking on the cell phone at a particular time and police can go and get those calls, those numbers. So yes, its critical to watch, how he might have handled the back pack, you know, manipulated a detonator, all those things are important. So yes, if people have video, share it. It might help stop the next attack. When you say that next attack, jim, we heard it over and over when it comes to these soft targets and that being the focus of these kinds of terrorist attackers, what is the reassurance the public can get time and time again when we ask how does this happen . And then we also know the soft targets given the intelligence perspective, given the tactical perspective on how the public, whether its in the uk or here in the United States can be protected. Right. Frances, well there is no sure bet that everybody can be totally protected all the time. We have to live our lives and we have to be brave about that for sure. But the chances of being struck in one of these attacks is very, very small as well. More things can be done. I think weve see attacks outside these venues in paris at the soccer stadium, at the airports prior to security in belgium, we saw it at istanbul and these are all in recent last year or so. So and theres many others going back in history. So we look at that, and we say okay, what about pushing that Perimeter Security out even if its lighter it has to be better. So what i would stay a guy walking across or lingering in front of the terminal there, in front of the Box Office Ticket area, how long was he there . Thats an important fact. I think all Police Officers and investigators want to know that. How long was he there . Was he there 30 minutes, 20 minutes, 5 minutes . Because that is an important fact. It may be you can help you defeat the next one. So bomb sniffing dogs outside that can walk up and you know, sniff people that are around there, sniff the area. A guy carrying a lot of explosives in a back pack, a bomb sniffing dog trained to do that, he can big that guy up right away and then officers can be brought in to question him and be moved out. You wont stop everyone but you can stop more. And maybe you know, higher surveillance level of the lighter perimeter with elevated officers watching. Things can be done that are not impossible to do. But ultimately its the crowd the terrorist is after, they were after the crowd. If the you keep that in mind when at these events living your life, keep that in mind. Dont always run with the crowd. You might want to think a little more independently, you cant get out of every line and crowd certainly, but you dont always have to be rushing to be in the middle of one. So just think about that. The terrorist is trying to get the crowd, if the crowds running the terrorist is trying to get them to run toward them. So keep your head on in the Public Events that you know, you dont need to just run willynilly in every direction. Think before you move. Certainly. Especially if there is confirmation in the reports initial reports we heard so far that maybe some of the 22 people who died and the 59 injured may have been injured through a stampede from that.
