Obviously the gunman is not here to answer these critical questions. They have to look back at who he knew, who he spent time with, who he spoke to, who he exchanged messages online with. And also some of the perhaps, the suspicious steps he may have taken before the shooting that happened here a week ago. Ill give you a couple of examples that investigators are taking a closer look at. He tried to buy ammo in bulk. He tried to purchase, reportedly tried to purchase body armor. Then also he gave or at least he added his wifes name in his insurance. So that theres Life Insurance policy. So theres really a huge amount of evidence that investigators have to weigh now as they try to answer that key question, that is still there today. Is why, its, it sounds simple, but really investigators have so much evidence to weigh. Especially as we hear from eye witnesses and then they review the tangible evidence. Tangible evidence, including the Surveillance Videotape from the pulse nightclub. This is internal imagery that investigators are looking at. Theyll be able to determine how he was able to reload, if he reloaded, what kind of weaponry he really did have with imhad i guess the sequence of events, thats the information theyre poring over. At what point if at all would that be revealed to the public . Its very tough to say. The assistant City Attorney in orlando said theyre going over all that evidence, including the recording of the 911 call that he made. When he actually called dispatchers, when he was reportedly in that bathroom holding several people at gunpoint. There are still the city is Still Deciding whether or not whether he will be released. Theres a state statute, any 911 calls related to the case would be released. But this is obviously a unique case. One that is getting interest from acrossthe ountry. From around the world. So it will be interesting to find out if that recording is ever makes it out into the public. That of course a Surveillance Video you mentioned a little while ago. That investigators are in fact poring over, that would be essentially a very disturbing window into what happened in that nightclub seven days ago. Because as you said, it would show where he went in the club. It would show maybe what he did, when he paused to make the phone call, to call his wife, the dispatcher, the producer. And then possibly a friend. Thanks so much polo. When we talk again id love for you to tell us about the history of the pulse nightclub. It is very much a part of this community here. It has a very delicate and poignant history, a story that thanks so much polo, appreciate that. So for more on what investigators are indeed going to be focusing on. I want to bring in cnn counterterrorism analyst phil mudd. So phil, polo talked about some of these red flags, if you want to call them that. Things about the past. Of the shooter. Which also would include reports about his behavior, while in primary school. But those necessarily wouldnt be in a background check, right . So phil, when you talk about red flags, these are things that have to be associated with a criminal background check . Thats right. I dont really see many red flags here, the only two i see, one is a legal issue, that is whether the fbi has a right to know for someone who is not under investigation today, whether that person is buying an assault rifle. The second red flag is simple the wife should have talked to federal officers and said im afraid about what my husband might do but the other stuff, fredricka, lets go in the opposite direction 300 million americans, are you going to start looking for people who may say things to workers that are bigoted, that relate to violence, that are maybe done online searches related for example to the attacks in San Bernardino . Those might be red flags when you look at an individual case, thats not the way to look at this you got to start with 300 Million People and say how do you boil that down to somebody who should be the subject of a federal investigation . And fredricka, i dont see much of that in this case. Okay. So thats the very complicated part. Because so many people ask you know what about the collection of information about an individual . How do you determine whether someone is potentially danger s dangerous . And to what degree . So you know, how would investigators, how would Law Enforcement try to anticipate or how would they be able to zero in on what some neighbors or coworkers would consider to be peculiar activities . In cases like this youve got to look for somebody to make a mistake, to talk to the wrong person online, for example an isis recruiter thats being watched by the fbi or the c. I. A. To talk to an informant on the street. To tell somebody that theyre going to commit an act of violence, like he told his wife and that person then calls federal officials to try to travel to a place like turkey, to go into syria to fight with isis. You have to look to somebody to make a mistake. When an individual in a country of this size just talks to coworkers, talks to family, maybe buy as weapon, you look back on this and do the afteraction as a federal official and you scratch your head and say, i know its not that rewarding, fredricka, but im not sure what you would look at and say i wish we would have done this differently unless you get no that, the case that congress has to deal with, about whether you authorize the feds to reopen cases when somebody tries to buy a weapon. Other than that, what this guy did doesnt get over the bar. And now you know, phil, weve been talking about omar mateens wife. Investigators are interested in talking with her further. But what determines someone, a wife in this case, involvement versus knowledge . Theres a couple of things to look at in this case, that is, what happened before, whether its clear and evidently shes given conflicting stories. Whether its clear she had an indication that he was going to commit an act of murder in this case, shes in trouble. Gout to call the feds when that happens. Theres a second piece that people talk less about, and thats called, what we used to call at the bureau, the fbi, 1001 violation, that is, lying to a federal officer. Once that investigation begins after the fact youve got to sit up and despite how embarrassing or painful it is, and tell the federal officers who are investigating the truth. If your story the day after is one thing and your story three days after is another, theyre going to come after you, thats a federal violation, theyre going to come after you for lying during that investigation. Shes got two issues, did she know something before . And did she lie afterwards . Cnn counterterrorism analyst phil mudd, thank you so much, appreciate it. Thank you.

From isis control. This after nearly a month of a u. S. Led offensive to free the city. Fallujah is 40 miles west of baghdad. It has been under isis control since early 2014. Cnns Senior International correspondent ben wedeman is live for us now in baghdad. So ben, while officials in the area are declaring victory, fighting is still raging in that city, isnt it . We just got back from there. We rode in an Iraqi Army Humvee to the center of town, saw a lot of destruction along the way. When we got to the center of town, which we were told had been liberated, what we saw was that fighting was indeed ongoing. In fact on our left one block over, there was a gun battle raging. Down the street we were on one of the main roads going through fallujah. About 300 yards away from us, there was fighting there. And on the street one block over to the right, we can also hear gun battle going on. Now the iraqi troops we were with seemed fairly relaxed, fairly confident that its only a matter of time that isis will be completely crushed in fallujah. But certainly what we saw is that its still quite a ways to go. Now we understand from iraqi officials that isis is still in control in the northern neighborhoods of fallujah. Now fredricka, whats significant is we were in fallujah for about two hours. We didnt see a sing the civilian. I did speak to one fighter who said some civilians had managed to flee from isiscontrolled areas. He described them as looking traumatized, hungry and thirsty. And desperate to get out of the city. Iraqi officials dont have a clear idea how many civilians are still stuck in the isiscontrolled areas. They said when i asked them today, several thousand. But its not clear whether theyre being used as human shields or simply hiding wherever they can. And hoping that the battle ends as soon as possible. Fredricka . Ben wedeman, thank you so much from baghdad.
