the other thing I am seeing on twitter from people who have been in sniper settings is that the reason that the sniper lifted his head may be something was not computing through the scope and he was trying to process/confirm.
The aerial photographs are incredibly helpful.
At one point in my life, I was in a building where a Big Politician was visiting. The Men in Black with Earpieces checked us out there.
It is stunning that the same Men did NOT have a man stationed on the building where the shooter was stationed. Maybe they did a sweep earlier, but that building should have been guarded if not stationed.
A casualty in the early day of any crisis is the truth. That said, Incompetence certainly was on display yesterday.
If this is true and it gets out as true, all hell is going to break loose.
