Blue Steel

A psycho killer scribes Jamie Lee Curtis' name onto the brass shells of some cartridges, loads them into his big revolver, then blows away strangers in a park. Detectives find the empty shells, so investigate JLC. Never mind that revolvers don't eject shells as semi-auto pistols do. Never mind that detectives would have known that the shells had been planted deliberately. Never mind that people don't write their names on cartridges. Correcting this film's technical inaccuracies would destroy its whole plot. Could the reason behind such silliness be a profound misunderstanding of the phrase, "a bullet with your name on it?"
