ARMED DOCTOR THWARTS SHOOTER IN PHILY HOSPITAL, a gun-rights case is born. “The question of whether it’s a good idea to arm doctors and teachers and others who work in places historically targeted by mass shooters has been recurrent in the news since even before the 2012 Sandy Hook Elementary School massacre in Newtown, Conn. . . . For one thing, police are still trying to figure out why Silverman was armed in the first place since bringing a gun to work is against the rules at the hospital.”

Yeah, the rules didn’t stop the bad guy either.
