I would have to think that if I had only one non lethal weapon to have at my disposal it would have to be one of a variety of Stun Guns that I could purchase.
Stun Guns have proven to be the most effective way to dispatch a would be attacker in the most efficient way.
If you choose to go around unprotected, well then be prepared to face the worst possible disasters that could happen to man.
I say, be prepared for the oncoming attack and get all of your weapons ready to do battle with those who would do us harm.
