Continuity mistake: In the scene where Jack rescues the worker from the warehouse, while lowering the victim - the rope is wrapped around the beam - but in the overhead shot as the floor gives way - the rope is only laying across the beam.
Chief Kennedy: Hey! What the hell is going on in here! Huh? I come back from tellin' a mother her son is dead, and this is goin' on, in my house, in MY house! We deal with this by stickin' together. We take it. We learn from it. And we get back on the god damn truck and that's how we honor Dennis. You got that? Anyone think about lowering the flag? Do it.
