Then mysteriously the shooter has guns and ammo given to them by an undercover fbi agent or agents usually the real shooters. They tell them to go to a gun free zone and then FBI always kills them before they get interrogated. Remember vegas shooting. Alot of reports of gunfire from other directions.
