Why wasn’t secret service on every visible roof!
It is fundamental that the roof should have been secured.
If not SS at least local LEOs.
It is SS responsibility to secure the entire area and any damn fool can see how many buildings with slanted roofs are within rifle shot.
A real sniper could have been more than 1000 yards away and they didn't even cover a couple of hundreds yards.
I've killed deer at 250 yards and I'm no where near a sniper type shooter.
The head of Trump's SS team should be investigated and at the very least fired if not more punishment.
