The clear and obvious answer is that you are afraid.
The word you're looking for is prepared. You don't need to be afraid when you're prepared.
So you prepare for every event that occurs to 1:100,000 Americans or so?
Better wear a helmet, I seen a woman got in the head by a rock the other , killed her. Her own fault for not being prepared.
Better never fly. Or ride in a vehicle
Better never eat out, or buy food
Just admit it, it makes you feel like a "big man" to carry a gun around. Let me guess you took one 24 hour course and fire 2 or 3 times a month right?
I'm retired military and I DO conceal carry almost every day and if I come across a situation where two bozos have guns out, I'm shooting you both and then figuring out which one was "the bad guy"
