I can't carry here in CA. I got a small folding knife today since every one has pit bulls running every where. I always carry a stick, but until today, had little to defend myself especially if there are more than one dogs in a group.
I don't have any pretense of being a cop. My CCW trained to evade, avoid and be a good witness first and foremost. In the gravest extreme and as a last resort, use lethal force to STOP an attack. Provoking an attack makes you the perpetrator in just about every case.
