 FAKE: When the crooks are breaking into the police evidence locker,  they freeze and shatter the padlock, which lets both ends of the  chain fall into the locker. In the same sequence, however, hands  grasp both ends of the chain and pull it out through the bars as if  there were two lengths of chain simply dangling into the locker and  attached to the padlock. At the same time, chunks of the "steel"  bars break off from the impact of the bolt cutters and the dragging  of the chains revealing the bars are made of wood.
