also with us, our law enforcement analyst, tom fuentes and matthew horace.ommissioner, thank you for being with us. yesterday, on this program, as we were covering what was happening in seaside, seaside park, new jersey, with the pipe bomb that exploded, luckily, the runners hadn't passed by yet, i immediately thought of the boston marathon bombing. what was in your mind? >> well, the same thing. tragically, some of the smaller events that occur day in and day out in towns and cities of america don't have the level of security that we have at a big event like the boston marathon. these are easy targets. >> so what has changed? i mean, in terms of, you know, a lot of security protocol around mass gatherings and big events, changed in the wake of the boston marathon bombing. what has changed the most? >> well, i think the amount of money being spent to try and secure these events. it's doubled and tripled in some cases. i've talked to event planners and not for profits that are really having a hard time making the security spend they need to. we have to look a

matthew horace and laura coates. i'm going to start with you.rd ana mention those court documents. that was the affidavit. and i'm going to read some more of the officer's state of mind from that affidavit. it says, this tulsa officer became emotionally involved to the point that she overreacted. in other words, she let her fear rule her actions, even though she could see no sign that mr. crutcher had any kind of weapon. so, as a trained police officer, she allowed fear to overtake her. what goes through your mind when you hear that? >> well, we've all been in situation s when fear was kind f overwhelming us. because these are some dangerous situations we often get involved with. but i think equally as compelling as that is that helicopter radio traffic that we heard, when you heard the officer who was in the air say, this looks like a bad guy. those sort of messages that are going into your ear in the middle of an incident sort of create a narrative that this is a situation that might be worse than you think it is. >> so she was hearing what wa

art roderick, matthew horace and paul crook shank with with me now. so, we heard from investigators that it's quite clear this off duty police officer really preventeded, the or saved the live of many by unloading on this stabber. he walked around and stabbed nine people. what more needs to be determine nd this investigation in order to figure out the motivation behind this aatlanta. >> i think the chief mentioned they had done a couple of search warrants and there are many more to come. they're going to be checking social media. to see how the suspect was community kating with and what they were planning. in the most recent case, we've reviewed cell phone record, twitter, other social media and seems like they usually leave a path on social media. so that will the first thing they're focused on today. >> no further comment, paul, on isis claiming this man was a soldier of the islamic state. obviously, investigators are going to look further into that, but how will they be able to determine whether he was a lone wolf so to speak, whether indeed he was

. >> get to matthew horace right now.vice president of fjc security services, a former atf executive, a perfect person to have with us this evening. you've seen devices like this one, right? very similar. does this appear to be an active device or can you tell from a picture if it's -- >> no from a picture, it very well could be a hoax device. it's non an explosive device until we declare it an explosive device. the only way we can do that is take it apart, determine what is inside the device. >> walk us quickly through how they would do that. don and i saw the robot that can be soenlt in without putting people in harm's way, that big sort of capture mechanism on the back of a truck. what would they do now with this device not knowing if it's a hoax or real? >> they make sure that the perimeter is secure. they'll take a robot, a hovering device over the device and try to detonate the device that doesn't create too much more havoc. then they'll dissect the device, determine what type of explosive, if any is inside the devi

and matthew horace and art roderick, cnn law enforcement analysts. so, art, you first. see in the video? how will investigators continue to analyze video from so many different angles there in the chelsea community and how will it help them piece together you may be responsible, how it all unfolded? >> it's a good sign that we have video of the explosion because and thest a pretty clear video. right there. so, they're going to go back and look at what happened prior, who was walking around there. who entered that looks lialleyw. i think placement of the device here is going to be key because it looks like it's kind of off the main road right there. but if they've got this good of video right now, i'm sure they have video cameras in other locations. that should link an individual with that device plant ed at tht location. >> then tom, what about the field of debris? again, we're looking at it slow motion there. with some distance right there in our foreground. how does that help investigators understand what kind of components device they're dealing with? >> i think it t

matthew horace former atf effective, art roderick and retired u.s., tom fuentes and former fbi assistant director, and juliet cayenne. good to see all of you. let's talk about the minnesota case first. we're still awaiting the press conference out of saint cloud, the shopping mall terrorized by the suspect who was wearing a private security firm uniform say police. and stabbed upwards of nine people before an off duty police officer shot and killed him. so i one exerciwonder, matthew, they go about determining wherein deed he is a soldier of isis as isis has claimed this suspect to be? how do they go about determining whether he was on a mission ordered by isis? >> as you know, early on in investigations, information is coming in fast and furiously. and as things evolve, things change havevery quickly. fbi will be checking social media, speaking to his family, trying to determine if he's a sympathizer, supporter or maybe not involved at all. so early indication sometimes change. they will determine it over the course of the next several days. >> and

. >> matthew horace, if and when the police release the video, your reaction to the timing on this? the calls have intensified each and every day. do they have much more time to wait frankly before releasing it in your opinion? >> often times the time line for investigations may not line up with the expectation from the media. what people should want is a thorough, final investigation. investigating, you don't want it done quick, you want it done right. hope to find in the next couple hours, next couple days -- [ inaudible ] >> thank you very much. as we continue to monitor the breaking news. this big rally in charlotte as the naacp comes out and says department of justice is investigating. thank you all very much. much more of this ahead. >>> also, politics ahead. final countdown for the first presidential debate under way. donald trump, hillary clinton meet face to face at hofstra university where we're coming to you live from today. coming up, what does it take to score big points in a presidential debate? you heard it before, a debate doesn't declare a winner but can cost someon

matthew horace is on the phone, cnn law enforcement analyst.y, a former atf executive who focused on explosives. what shimon also reported is on the pressure cooker that didn't detonate, there was a cell phone. it was a cell phone that was attached to, obviously, at some point, try to detonate this device. what are they doing as they've taken it out of the area and doing forensic work on it? what can they tell aside from the pressure cooker and where it was purchased, what can they tell when they take apart the bomb? sbl >> we talked about this early. there are things as small as wires we can take codes off of wiring to determine where the wire might have been purchased. what kind of instrument or device it may have been in before used as a component in an iud. obviously, the cell phone, where did they come from, who purchased them and why were they attached to the device? we said the video would tell the story. the most expansive network of cameras in the world. there was no way in the world we wouldn't be able to figure out who brought the ba

bob baer, math rthew horace, wh managed explosives investigations for the atf. matthews through what they're doing right now. the fact that, frankly, they're lucky to have this pressure cooker that did not detonate last night. therefore, it is a plethora of information for you. >> you're absolutely right. they are trying to establish where the device came from. they're using date codes and other identifiers to determine where it was purchased. they're trying to ascertain what explosive, if any, is inside the pressure cooker and if there is, in fact, anything inside the pressure cooker. also, what is the device made out of? the detonation device looks like a cell phone. the battery, wire. they're trying to use all of that to try and make sure they can figure out where the device was manufactured and who manufactured it. >> tom fuentes, when you look at what the fbi is doing now, can you walk us through the proess ther -- process there, in terms of what they did last night and what they'll be doing today? is the key piece of evidence they can get the cell phone attached t

also here, cnn law enforcement analyst matthew horace, former atf executive. we are talking about this video. the police chief says he will only release it if there's a compelling reason to do so. is there a compelling reason left not to do so? >> no. they have every reason to release the footage but if you are the police chief who previously held a press conference and said here's what happened after viewing the videotape and it's completely opposite of what the family has said, now we are revealing that actually it's inconclusive, they are trying to carry on what they earlier said and that's not the reason to avoid transparency. it's not about the investigation coming undone. it's about a p.r. issue they are facing. keep in mind, you guys know there's a law coming into effect in a few days that will prevent you from releasing any footage barring a court order. and the chief's statements track the language of that statute now. >> mark, i want to get your take. from your perspective, do you think it should be released? what do you think's going on with the dec
