Dozens of Local Police Officers Were at Trump’s Rally. Very Few Were Watching a Critical Area.

A key question after an assassination attempt on former President Donald J. Trump a week ago is why the Secret Service excluded from its secured zone a nearby warehouse the gunman used for his assault.

But another possible flaw in the Secret Service’s plans for the campaign rally at the farm show grounds in Butler, Pa., is emerging. The protection agency expected the sizable contingent of officers from local law enforcement agencies to contain any threats outside of the secured zone but assigned almost all those officers to work inside it, according to numerous interviews with local law enforcement and municipal officials.

None of the law enforcement agencies that assisted the Secret Service that day — the Pennsylvania State Police, the Butler Township Police Department, the Butler County Sheriff, Pittsburgh Bureau of Police or the multicounty tactical teams — say they were given responsibility for watching the zone outside the Secret Service’s security perimeter.

More specifically, the local law enforcement officials say that none of them were assigned to safeguard the complex of warehouses just north of the farm show grounds. The gunman was able to use the roof of the warehouse closest to the stage — about 450 feet from the podium — from which to shoot.

“I am going to defend those guys, because it wasn’t their job to secure the building,” Richard Goldinger, the district attorney in Butler County, who oversees the multicounty tactical teams that were used on Saturday.

Rather, an overwhelming majority of the dozens of local and state officers called upon to aid the Secret Service were given other duties at or inside the secured perimeter — an area that was protected by a fence, metal detectors and the Secret Service itself.
