All should note that the perp in this case is being treated for *multiple* gunshot wounds.
I would suggest that the homeowner made a mistake by “going hunting”, instead of finding a covered position and letting the perp come to his field of fire. I would prefer fewer hits on the perp if I don’t get any myself.
As a rule of thumb, the perp has adrenaline, and maybe alcohol and drugs going for him, so I would never assume my bullet launcher will be enough, especially if he can return fire.
Finally, if I put several into him, and he still has enough chutzpah to charge, he is going to run headlong into my backup knife, and that will cool his jets.
I just helped a friend buy his 1st gun. Glock 19.
He started talking about a Mossberg 500 and how he was going to. “rack it” and that would be enough to scare an intruder.
Told him “Nope. Racking is the same as sending a ping to his radar”
Gun should already be loaded but, in any case, if he comes to you ...empty whatever’s been weighing heavy on his chest and the gun, reload repeat.
