Snopes
Funny, you believe Trump when he says he would run into a school unarmed with an active shooter but you doubt Snopes... classic.
Who here would run into a school unarmed to the sound of gunfire? I'm not saying I am as brave as Trump, but there were already adults unarmed in the school, and they were getting shot. Hand gun, I would. Shotgun or AR I definitely would. Unarmed? If I did, it would probably be in an area away from where the gunfire is coming from with the intent to get as many out as possible and get some intel to give to the arriving officers. I don't know that I would.
