Anyway, I will amend my statement to read that adults shouldn't attack other adults with their fists or otherwise. I hope that is general enough for you.
If the police are too busy fighting serious crime, I'm sure they will put the water bottle attacks off until they finish.
A water bottle thrown at the body is not going to break your jaw, smash in your eye socket, give you a concussion, knock you out, or give you permanent brain damage (especially if your head hits the floor while you are unconcious), all of which a good punch could do.
