Snowballs in DC

You may have heard of the snowball fight at 14th and U, 2 blocks from me. I actually wish I'd heard about it while it was still on. It sounds like it was just some spontaneous fun for a bunch of people (around 200 ) who really never get to see much snow. That is until a snowball hit the car of an off-duty police officer. He then got out of his car with his gun drawn. He was in his personal vehicle and not in uniform. So of course someone calls in that there's a guy on the street with a gun and more police show up (the station is just next door to me). So yeah, it was all fun until the stupid DC cop behaved like a moron. Really, only in America would this happen...
