Visible crew/equipment: After the '60 seconds test' Stan goes to the bathroom. After Ginger says 'I really wanna help you Stan' he moves to the towels. Watch the mirror to the far left of the screen and you'll see the boom mic to the top-right of the mirror just before the shot changes. (00:29:40)
Visible crew/equipment: When they are about to attack the bank, there are Humvees that are travelling along the roads. When they beep someone off the middle of the road, as the second one goes by you can see the reflection of the camera in the side door.
Visible crew/equipment: When Gabriel and Stan make the deal he's sitting at the computer and he swivels round to face the screens. When he's taking his jacket off look to the upper right part of the screen. The boom mic is just poking down far enough to be seen and wobbles continually. (00:36:05)
Answer: JT is exactly who he says he is. He leaves a body behind to fool the FBI/CIA into thinking he is dead. Jackman would have believed it too had he not seen him heading down the stairs and the surgically altered corpse. Berry was not hurt, the wire, the DEA story and her getting shot were all parts of a ploy for Jackman to trust and confide in her, making it easier for Travolta to make Jackman do what he wanted. Travolta didn't actually kill any hostages directly himself, (though he did put them in that situation, he is by no means Mr. Innocent) - had the police done what he asked, no one would have been hurt at all. So basically, he IS a good guy, but his methods are somewhat morally lacking.
