People were having a snowball fight in the street (it's not like anybody was out driving) and hit a plainclothes cop. He pulled out a gun. He apparently also didn't bother to identify himself as a cop until another officer (in uniform) arrived and pulled out his gun on the first cop and made him "drop it and let's see some ID." (source) Naturally, someone had a camera, recorded the conversation with the cops, and put it up on YouTube. Idiot cop: "Yes, I did because I got hit with snowballs." Sensible cop: "Go back to your snowball fight, call the station if there are any other problems."
