Where would the position be? The school is rather large, no? And he was not on the ground floor. Is that right?
That would be up to him. I wasn't there. All I know is NOT going after the shooter was the wrong thing to do. There was no chance of saving lives with the way he stayed outside hiding behind a car. Why was he paid all those years to do a job and when the time comes when he's really needed, he does nothing?
