The Vice-President claims that AR-15s are harder to use:
If you want to protect yourself get a double barreled shotgun. Have the shells, a 12 gauge shotgun, and I promise you… I told my wife; we live in an area that’s wooded and it’s somewhat secluded. I said Jill,if there’s ever a problem just walk out on the balcony put that double barreled shotgun and fire two blasts outside the house. I promise you whoever is coming in is not going to… you don’t need an AR-15. It’s harder to aim, it’s harder to use and in fact you don’t need 30 rounds to protect yourself. Buy a shotgun. Buy a shotgun.
