After Sam is caught in the bear trap, his shoe is either on his foot or still in the trap, depending on the camera angle.

The film takes place in Detroit, Michigan. Lonnie is on death row for being the "Pontiac Killer", however the State of Michigan abolished capital punishment for state crimes in 1846. Lonnie also couldn't be executed in the state even by the Federal government since a 1963 state constitution amendment also abolished federal capital punishment in the state. The last person to be executed in Michigan was in 1938 by the U.S. Government.
Sam goes to Detroit Police headquarters to investigate the Pontiac Killer. Pontiac, Michigan is 30 miles north of Detroit, and all crimes there are investigated by the Oakland County Sheriff's Department.
