Factual error: When the crooks are on their getaway from the bank raid in the hearse, you can see 1960s cars through the back window when this scene was set in 1950.

Continuity: When the crooks are climbing over the wall into the police station yard, when they are on the pavement, the ladder dosen't reach the top of the wall. But when seen from inside the police station yard, it reaches above the wall and looks like a different ladder.
