Calling the Van Nuys LAPD station, I claimed to be from the DMV and said I was compiling a new database. “Is your Requester Code 36472?” “No, it’s 62883.” (That’s a trick I’ve discovered very often works. If you ask for a piece of sensitive information, people naturally grow immediately suspicious. If you pretend you already have the information and give them something that’s wrong, they’ll frequently correct you—rewarding you with the piece of information you were looking for.)
