This is a marvelous lesson in some of the advantages of concealed carry.
CC sends the “degree of difficulty” of armed robbery through the roof, and gives huge advantages to the cc-carrying victim, even if the robber is brandishing a gun, pointing it at the victim, and the hammer is back.
First of all, the robber wants to rob, not kill, then get away. He does not want to be witnessed, or have somebody sneak up behind him. And he has to be aware of an escape route or two, and that they remain open.
So his attention is all over the place, looking in all directions, not just the victim, ready to bolt at moment’s notice for several reasons, and, often as not, he is high on some drug or alcohol, further diminishing his capacity.
But the cc victim is focused. Find an opportunity, draw my gun while taking it off safe, and light the robber up. Your intent is not to rob the robber, but to shoot him. Hopefully a bunch, not once at a time with a pause to see if your bullets have “worked”.
The cc victim can shoot any time he wants. If the robber says he has a gun, or holds the gun in his pocket, or is distracted, or when he reaches down to get valuables you have tossed on the ground, or even when he is leaving.
(Oh, and the big secret, that a lot of guns used by robbers don’t even work.)
It’s comparable to waiting for an opening when you want to make a left turn across traffic. If you see an opportunity, you can take it or not, or wait until a better opportunity. Or even wait for a red light in the opposing lane, and for a nice person to stop and leave you a gap to cross.
The tactical advantages of cc are huge. The dad in this instance did not want any risk to his kids at all, so at first cooperated, and only shot when the robber was trying to get away. He did right. Judgment call as to whether he did right enough times.
