FBI SURPRISED! they knew he was there and gave him time to do it and then took him out immediately, we all heard the comments during the maylay, the shooter is down seconds after Trump went to the floor. Pretty quick, which means they knew where he was and had him in thier sites, lying scumbags!
You are CORRECT.
4,5,6 shots,pause, louder,single shot.
Shooter is down.
SECONDS between shooters quick shots and sniper kill shot means spotter/sniper already zeroed in on shooter.
According to a witness, SS was aware of them pointing to the man on the roof with a rifle. Did nothing until AFTER shooter got off several rounds.
