Here is the most complete video I've seen of the now-infamous incident in which a plainclothes policeman in Washington, D.C. pulls out a gun after his Hummer is hit by snowballs during a street snowball fight. The D.C. snowball fight gun video is five minutes long and although it stops at various times, it shows what seems to be a complete view of the scene.
The cop doesn't immediately identify himself as a police officer, and uniformed police later show up in response to calls about a man with a gun. The plainclothes cop seems to calm down once his uniformed brethren arrive. The crowd, which heard about the planned snowball fight via Facebook and Twitter, start shouting, "You don't bring a gun to a snowball fight!"
The Washington City Paper has an article on the snowball fight gun incident based on eyewitness reports.
