I don't call the police because I've never, ever found them helpful. This applies not only to issues with the bike, but with the car, with my home, and with my person. They might, if they're in a good mood, take and file a report. They're more likely, in my experience, to ask you WTF you were doing riding in the road.

Cops are the biggest street gang in the nation. It pains me that I have no choice but to contribute to their salaries.
