More on stopping power...
I have told this a few times and some may have seen it. It goes along with this. A buddy of mine, undercover LEO, was deep into an outlaw biker, drug, fighting, drinking, group of very bad people. They were very used to hurting and being hurt... that is one important difference between BGs and the rest of us. They can have all the front teeth knocked out get cut and grin and cuss ya back...
The LEO was bringing down a big drug bust and his partner, another undercover LEO was first on the scene as a uniformed cop. There is a long story but here is a short version.
Shots are fired inside building before police get into position. BG runs out of building straight at partner, who is in uniform with shotgun. BG has pistol and is running straight at LEO, all other cops have dived for safety at sound of shots. LEO puts every round of slugs and buck from long mag 12 ga. 870 into chest of big BG. BG takes every round, drops pistol, and kills LEO with the empty shotgun by sledging LEOs head and neck with empty gun. BG runs off for a long ways, over 100 yards and dies with a chest full of mush, slugs and buck.
It can be a very long and deadly 5 seconds, which is a point of the story.
Points: BG was used to hurting and being hurt. BG was probably hopped up on drugs and alcohol. BG was big and strong. BG was pumping adrenaline and he was already IN a gun battle from inside when he ran outside. Even a 12 gauge, many shots, may not stop a BG fast enough.
As the article says, shoot, get out of the way and keep shooting and as was inferred... when the long gun is empty keep out of the way and fill the BG with pistol rounds...
