Burglars just broke in
An elderly woman had just returned to her home from an evening of religious service when she was startled by an intruder. As she caught the man in the act of robbing her home of its valuables, she yelled, "Stop! Acts 2:38!" [Turn from your sin]

The burglar stopped dead in his tracks. Then the woman calmly called the police and explained what she had done.

As the officer cuffed the man to take him in, he asked the burglar,"Why did you just stand there? All the old lady did was yell a scripture at you."

"Scripture?" replied the burglar, "She said she had an axe and two 38s!"

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"
