On December 26th, a pair of crooks decided to rob a gun shop in Georgia. It didn't go well for them. Here's a news report with some of the details.
The impressive thing is how fast, and how well, the gun shop owner reacted, as shown in the surveillance video camera footage below. He'd clearly had some good training in the use of his weapon, and did so very effectively. Note the rapid reload after he empties his first magazine, before he goes to check on the fallen robber.
Nice work, sir! That looked to have been a head shot, too, on the fallen robber, or perhaps a hit on the spinal column. One doesn't collapse so suddenly unless the central nervous system is taken out. A heart shot wouldn't have done it.
EDITED TO ADD: The deceased perpetrator has been identified - and, to judge by the descriptions from family and friends, you'd think he was a choirboy, if not an angel. Why am I not surprised?
