Want your fellow Americans armed to the teeth? OK, but consider this: A bystander witnessing a carjacking in Houston Saturday night opened fire and missed the assailants but shot the victim in the head, police say. KHOU reports that a guy was being attacked by two men at a Valero gas station in north Houston when the bystander drew his weapon and fired. The bystander then snatched up his shell casings and fled, and police found the victim's Chevrolet pickup truck about a mile down the road with the attackers long gone. The victim is now in hospital in stable condition. See a TV news report on the story at ABC 13. Hat tip, Raw Story. (More vigilante justice stories.)
