Clinton is right when he says, "most studies show that the majority of weapons carried for 'self-defence' wind up being used against the person they were supposed to defend... "

That goes for any weapon, even bear spray.

Learn to walk with confidence. Always know who is behind you. Cross to the other side of the street if a stranger is appoaching and the streets are empty. Carry your keys in a fist with the jagged edge out. If attacked, scream and go for the eyes. When they put their hands up to protect their eyes, run. Keep screaming!
