The assassination perp used an iron sight at 140yds.
Used a drone hours beforehand to scout the area, around feds, unabated.
Secret service didn't attend the local law enforcement security meeting that morning where they establish their lines of comm.
Counter snipers were originally not authorized for the event, and when they were they only scouted the area a day before.
The local law enforcement taking pictures of the guy an hour before the event with a range finder.
He rode a bike from his van filled with explosives a mile to the event with his gun.
The kid aimed a gun at the officer who got on the roof and within seconds swung around and started shooting the president? That accurately? BS
This is getting too crazy to blame on incompetence and chance.
