In the aftermath of the Texas church massacre, former Vice-President Joe Biden, in blind conformity to the Democrat anti-gun line, stated that the armed citizen who shot and wounded the deranged shooter before law enforcement could get to the crime scene should not have been able to legally arm himself with the AR-15 rifle that ended the rampage. Presumably, Biden would have preferred that Mr. Willeford, a previously certified NRA firearms instructor, have used a double-barreled shotgun, as Biden counseled in 2013.
I suspect that Mr. Willeford would have used whatever weapon was available under the circumstances, but given a tactical choice, selecting a double-barreled shotgun would not have occurred to him – or to anyone else with a lick of sense and even a rudimentary knowledge of firearms. Law enforcement and the military make limited use of shotguns (pumps or semi-autos), but not in situations like Mr. Willeford faced.
As a practical matter, there is probably not a weapon Mr. Willeford could have chosen that would have been more suitable than an AR-15 for the stand-up task he undertook. The Second Amendment protects our right to make that choice. Biden should have kept his mouth shut rather than further reveal his partisan stupidity and ignorance of the Constitution.
