In DC last Sunday an 11 year old boy was riding his bike when he was attacked by 3 loose pitbulls. A neighbor retreived his gun and shot one of the dogs. While he was attempting to free the boy, a DC cop showed up to shot the other dogs. He also arrested the neighbor for violating DC handgun ban. Somewhere along the way, the boy was also shot in the foot. Wapo wouldn't state which shooter hit the kid so it's a pretty good bet it wasn't the neighbor.
The moral of the story being, under gun control, don't come to anybody's aid. Just let them suffer until the "government" arrives.
