Corrected entry: At the beginning of the film where John breaks into Simon's hide-out, John points his Beretta 92 sidearm at Simon to make Simon tell him where the hostages are, he then cocks the weapon when Simon doesn't tell him, but we saw John just before running on the roof and in the building shooting bad guys with the same gun - the gun would already be cocked because the Beretta 92 is a self-loading firearm, when a shot is fired the power of the bullet's explosion forces the gun's slide back to eject the spent case, cock the hammer, and load a fresh round into the gun's chamber. Even if he reloaded off screen with some rounds still in the magazine the hammer would still be cocked or in the case of if the gun was empty the slide-stop would engage, holding the slide open and the hammer cocked.
Corrected entry: Right after escaping from prison, Simon Phoenix is at the computer thingy and he says, "Damn, I'm possessed" without getting a citation for violating the clean language act or whatever it is. Yet later he says "damn" again and gets a ticket.
Correction: The second time he says God-Damn, and that's why he gets a ticket.
Corrected entry: In the scene where Simon Phoenix is operating the machine he says "Damn, I'm possessed" and he is not fined.
Correction: The machine was too busy processing the information Pheonix was asking for; it fined him when he was only talking and not typing.
Correction: He probably released the hammer manually by holding it while depressing the trigger. This would be done by anyone trained with firearms to prevent an accidental discharge, especially as he moves from the roof down into the building. Just because we don't see it..doesn't mean it never happened.
