I've been trying for some time to get good video coverage of a shot fired by a Jefferson County, Colorado deputy in January this year. He was defending himself against an attack by two armed robbers at the time.
I've just come across this video report. The deputy may not have been a top shot, but he was certainly a very lucky one! Watch in full-screen mode for best results.
That was a pretty extraordinary outcome. The only one I've seen that was remotel comparable was two bullets I found in southern Africa that had hit each other in mid-air and fused together. I've seen similar incidents reported elsewhere, so that's not as unusual as I'd first thought; but it's still pretty rare.
