A man went to the police station wishing to speak with the burglar who had broken into his house the night before. "You'll get your chance in court," said the desk sergeant. "No, no, no!" said the man. "I want to know how he got into the house without waking my wife. I've been trying to do that for years!"

A staged wedding to bust dealers
As supposedly reported on CNN:

Undercover police, staging the wedding of "a drug kingpin's daughter", let it be known on the street that dealers were "invited" (i. e. Expected to attend).

The bride and groom were police, as was the band, bartender, and about half the guests. The band playing at the wedding was "S. P. O. C." (COPS, backwards), and the wedding went through the full ceremony, including the dancing afterward.

The long-sought dealers were arrested after the "band" took their break. The last song the band played before taking its break? "I Fought The Law, And The Law Won"
