let's bring in justin hastings. he's a terrorist expert currently in hawaii. we have a situation that we've got this guy taking hostages, but he doesn't have the right flag. he's allowing hostages inside there to receive cell phone calls, on their mobile calls. he's let five people actually manage to escape, if that is in fact what has happened. he's allowing people to post on facebook as well as twitter. is this adding up to a profile of a guy who isn't really in control of what's going on? >> caller: it doesn't seem very well planned. it depends on what his actual goal is, if it's to get attention for his cause then it's suck sided beyond his wildest dreams. if it's something else, he's got a problem. he didn't control the exit. he didn't control information in and out of the building. and he does sort of sound crazy to people who overhear him. it may be something drove him to do this without a lot of planning, without a lot of forethought. >> that's what you said earlier when you joined us, the whole thing by isis, if this is indeed related to that, which i
