The truth about violence

Sam Harris gives some basic principles of self-defense:

You are under no obligation, for instance, to give a stranger who has rung your doorbell, or decided to stand unusually close to you on the street, the benefit of the doubt. If a man who makes you uncomfortable steps onto an elevator with you, step off. If a man approaches you while you are sitting in your car and something about him doesn’t seem right, you don’t need to roll down your window and have a conversation. Victims of crime often sense that something is wrong in the first moments of encountering their attackers but feel too socially inhibited to create the necessary distance and escape.
