The football coach who died sheltering students with his body was also the school security guard. I've read Cruz wasn't detained for 2 hours. Liberals would tell you it's a good thing that security guard, who was at the initial point of contact and sacrificed his life, wasn't armed. Not good for him or anyone shot after his confrontation.
He escaped the school campus by blending in with other kids running away from the scene. With 4500 kids on that campus, he probably was NOT the only kid wearing a maroon/burgundy shirt yesterday.
