Possibly the officer was hanging on to the roof with just his hands, had pulled his head up over to get a view but his feet were hanging down. Possibly overweight and had to drop back to the ground. To pull his weapon he would have had to hang on with one hand. 2 minutes, 1minute 30 seconds…
Fire shots in the air. The snipers will look toward the gunfire and see perp.
Trump will be tackled by SS.
Or use a radio channel going directly to all SS and other law enforcement.
Say something like Cover Braveheart Now !
Shooter in range!
Get down! Get down!
FWIW, our much maligned Officer Doughnut peeking over the edge of the roof probably saved Trumps life.
Not by daring heroics perhaps and probably not even by intention, but he almost certainly did.
Like Woody Allen used to say - 80% of success in life is just showing up.
On that day, Woody's 80% solution for success carried the day and just showing up was just good enough. Barely - but enough
Just sayin’
Perhaps perp had been supplied with a password to identify friendlies?
Actually, with 30,000 people outside in the immediate area, firing into the ground would be a better choice.
