A local policeman did spot the shooter before the attack but failed to stop him after Crooks aimed his rifle at the officer, forcing him to back down a ladder.
Michael T Slupe, the Butler County sheriff, said the officer was gripping the edge of the roof and could not reach his gun when Crooks aimed at him.
โHe lets go because he doesnโt want to get killed,โ he told reporters.

Local counter-sniper team was inside building where Trump shooter climbed on the roof and opened fire
A local police counter-sniper team was stationed inside the building where attempted assassin Thomas Crooks climbed on the roof and fired on Donald Trump, law enforcement sources told The Post.
The building โ the AGR International Inc. factory in Butler, Pennsylvania โ was being used by local police as a โwatch postโ for snipers to scan for threats as the former president spoke onstage only 130 yards away, according to sources.
Cops were inside, but not on the roof during the shooting, sources said.
