If a situation evolves, through no unwarranted action of your own, you did not introduce or involve a weapon in said situation. The other parties merely choose poorly. This is not your fault.
I carry every minuet that I am awake. I proceed with my daily activities as if I did not have that extra 4# of weight on my hip. Likewise I don't go though my daily activities with a chip on my shoulder to match the potential of the weight on my hip.
If a problem is directed at me, I did not introduce the [my] weapon into the problem. I did not escalate the situation by being in possession of a handgun. The other party is the one that may or may not have bitten off more than they can chew.
