The reality was the shooter had hit everyone he was going to hit before anyone could muster even a token response.
Even the police who had rifles could not locate him exactly to suppress him and remained confused to location and number of shooters a full hour into the incident.
We are talking five hundred yards here, where a human body is smaller than your front site post.
The shooter didn’t have any marksmanship skills. Shooting at 22,000 people crammed into a restricted space is like shooting fish in a barrel.
