There were about three interviews I saw claiming there was a shooter in the water tower, for example. But given the way the mind works, they could have easily heard the shots, turned to see a water tower, and made the assumed connection that must have been from where they came. The mind could go as far as fabricating that evidence in mind’s eye with certainty if it was the belief of the person. Which is why witness testimony is often unreliable.
The incontrovertible fact is that MUST SECURE areas were never secured.
Absolutely.
The big question is WHY they weren't. Incompetency or Intent. I lean toward the latter.
One,of the videos shows a black dot on top of the water tower at the time of the shooting and a few seconds later that black dot is gone.
