Stupidity: When White and Exley meet outside the motel and realise they've been set up, White suggests they leave, but Exley says it's too late. It wasn't even close to too late. There were no other people around, they had cars and there was a road right in front of them. Then they decide to go trap themselves inside the motel. It seems like they wanted to be shot.

Directed by: Curtis Hanson
Starring: Kevin Spacey, Russell Crowe, Guy Pearce, Kim Basinger, James Cromwell
Deliberate mistake: When White almost fights with Exley in the street and is pulled away, the public mailbox by the side of the road is all blue. Mailboxes back then were red on top and blue on the bottom.
Ed Exley: Why'd you become a cop?
Jack Vincennes: I don't remember.
Trivia: Kim Basinger won the Academy Award for Best Supporting Actress for her role as Lynn Bracken, even though she's only in the film for 15 minutes.

Chosen answer: A 12g shotgun blast at that range would cause an incredibly bloody death, especially as there is a good chance it hit the man in the face. Exley has killed a person in the line of duty before this, but not in such a spectacular way. And while he may not have meant to kill him he chose to shoot over letting the man escape.

The scene was building up tension beyond "Will Ed catch the Night Owl suspect?" Ed has lost his glasses and gets to the elevator as the doors close. He fires blindly into the elevator; for a split second, Ed took a risk: he could've shot an innocent bystander. His career flashes before his eyes. IIRC, it was filmed in a way to imply Ed didn't actually see the suspect get in the doors. The doors open. Ed realises the risk was worth it. This is a pivotal point in his character development.
