Ananova reports that a British man learned the hard way not to shoot a policeman with a water gun.

A man is set to face magistrates after an incident in which a passing policeman was hit in the face by a stream of water from a high-powered novelty water gun. [...]

Road worker Gary Parker, 26, maintains that if he hit the officer it was accidental and has claimed the policeman was "out of order" by using CS spray to arrest him.

That sucks getting sprayed by pepper sprayl, but had this guy done this in say, Chicago, he would probably have been dragged into an alley and pistol whipped.

Did the officer over-react? Maybe. Perhaps a normal person would just laugh it off, but that doesn't excuse the fact that this guy was spraying a water gun around without looking where he was aiming.
