I'm sorry, but I guess I would like to have something that I could try and defend myself with. I think we are having a difference of culture here. I'm was country kid, not a city kid. I think there is a big difference there. I was brought up to take care of myself. I agree the younger the kids get, the less likely they could throw hard or açurately. When you get to 9-10 years old, a country kid has thrown a lot of rocks. If they understood when to throw the cans at the attacker would be another question. Don't throw unless you can't escape or evade.
