Listen: Being a cop doesn't automatically make someone a good driver. Yes, law enforcement officers are trained for pursuits and tactical maneuvers, but that doesn't mean they're all geniuses behind the wheel.

We saw that this weekend with the boneheaded move by the D.C. police boat out on the Potomac River. Sure, that was on the water, but there are plenty of examples of police screw-ups on the road as well.

That's the question of the day: What is the worst example of police driving?

See if you can find the most deplorable examples, preferably in video form, of vehicular law enforcement incompetence out there. There are probably plenty to choose from.
