That picture alone is very damning. It’s an open roof that should have been easily seen from a helicopter or drone.
It is hard for me to believe that the sharp-shooters perched on the adjoining roof did not see and have the assassin in their sights prior to the shooting. He was seen by those with less advantageous vantage points! They had straight line-of-site positioning and it was their job to be searching the area for potential shooters. It seems more plausible that they had him in their crosshairs, but someone of higher authority refused permission for them to preemptively take a kill shot. They had no problem taking him out quickly but not until he had opened fire. Let’s see if anyone’s head rolls or who will be the scapegoat!
I wonder if Biden's SS detail follows the same one-free-shot rule. I bet not.
