"You'd have a lot of people that would be armed, that would be
ready. They're professionals, there may be Marines that left the Marines, that
left the Army, left the Air Force... You'd have a lot of them and they'd be

was well guarded from the standpoint of having pretty much professionals with
great training, I think they wouldn't go into the school to start off with. I
think it could very well solve your problem."
Donald Trump, saying that armed teachers are the answer to school
shootings
