I wonder what are the odds of a) being confronted by a life-threatening weaponator and b) simultaneosly having a weapon on or near your person, and c) effectively using that weapon to disable your attacker?
Secondarily, I wonder what are the odds of a) having a gun in your house for "protection", b) having that gun loaded, and c) having that gun found by either a curious child/grandchild or a temporarily enraged adult and, d) harming/killing a loved one?
I will check on the statistics.
