Responding to critics who ridicule his insistence that shotguns are the best home defense weapon Vice President Joe Biden warned MSNBC's Morning Joe of what he perceived as the dangers of using an AR-15 for home defense.
The Vice President's concerns focused mostly on the idea that a round fired from an AR-15 may penetrate through a wall and hit a child in their bedroom. He insisted that would not happened using a shotgun.
"You know, they make fun of my saying about use a shotgun if someone's invading your home - guess what, use a shotgun on someone invading your home and you don't kill your kids - use an AR-15, it goes through your wall and it can kill your kid in the bedroom" Biden said.
Biden made no mention of self-defense ammunition designed for the AR-15 in order to prevent wall penetration.
