Here's some footage that's going around today. In it, a rowdy crowd celebrates the Giants win with vandalism and a bonfire. Then a car comes through the crowd and a mob swarms the car and driver until police show up. Holy shit.
Here's bonus—and extremely choppy, ha—helicopter footage from KTVU in San Francisco. I thought all those wine-drinking, pot-smoking, pinko hippie homos in San Fran were of the gentle variety.
