Pawn

An old gangster, with a hard drive containing records of who he paid off, is targeted by a competition between dirty cops, internal affairs, etc. The dirty cops hire a thug to get into the safe (in the back of a diner) at midnight. But he brings his friends and goes too early for the time-release lock. Another crooked cop shows up (for uncertain reasons). The shooting ensues and during hostage negotiations the thug tries to put the blame onto an ex-con who just got out of jail, so that no one notices the real target is the hard drive.
