Man uses AR15 to repel a violent home invasion:

The masked teens — a 15-year-old and two 16-year-olds — approached three residents around 4 a.m. Monday at the front yard of a home just outside Conyers and tried to rob them, the Rockdale County Sheriff’s Office said.
One of the would-be robbers took out a gun and fired shots at them before one of the residents returned fire, authorities said.
“The victims of the attempted robbery were all uninjured, but the three attempted robbery suspects were all shot during the exchange of gunfire and succumbed to their injuries, one on scene and two at a local hospital after being transported,” the sheriff’s department said in a news release.

Many media outlets are omitting the fact that the teens went into the robbery blazing away with handguns, trying to spin this story as “Man kills teenagers with a black rifle1”.

Given the increasing number of home invasions and group robberies (see also: downtown Minneapolis) going on, it’s useful to remember that military weapon designs are designed, not to “kill as many people as possible”, but to not ever jam, and not run out of bullets before your attacker runs out of attack.

Mission accomplished.
