In today's world? A significant chance...
I too, avoid troublesome places, but that is no guarantee that trouble will not find me.
I choose to be left alone, and in Wally World parking lots I'm sure that I do not look like a 'first pick' victim...that's still no guarantee that I won't make a couple of dirtbags' quick hit list.
I am always armed, I trust no one, and my head is always on a swivel...again, no guarantees.
If confronted, I will react quickly and violently...many times the decision will have to be made in just a second or two. I want to go home and continue on with life, but if it is my time...then it is my time. I will not let some dirtbag hold me hostage, make me plead for my life, or rob me and THEN decide to shoot me anyway. I don't go to bars or wild parties. I don't do drugs or even drink much any more. I'm just not in the places that trouble is almost guaranteed, but I do move around in the city where the bad guys roam around looking for easy 'stuff'.
I'll take my chances and defend my right to continue on with life, and let the chips fall where they may.
