Given the evidence, I'd say this cop was at best, a bit too exuberant in his enforcement of the law, and at worst is a liar who threw a guy off his bike for no reason. Does this mean I've lost faith in the police? Nope. Does it mean I don't like em? Nope. It just means that I accept the fact that not every cop will be perfect. I do however believe there are more good cops than bad.
