David Zimmermann writes for National Review Online about the congressional group that investigated attempted assassinations of President-elect Donald Trump.

A bipartisan House task force that investigated the assassination attempts against President-elect Donald Trump released its final report of the shocking incidents on Tuesday, saying the Pennsylvania attempt was “preventable and should not have happened” while crediting the Secret Service for preventing the one in Florida.

The 180-page report cites “various failures in planning, execution, and leadership” ahead of the shooting at Trump’s campaign rally on July 13, including the Secret Service’s failure to mitigate line of sight between the rooftop on which Thomas Matthew Crooks lay and the Butler event stage. That day was characterized by fragmented communications between federal and local law enforcement, among other security lapses.

Instead of narrowing the problem down to a “singular moment or decision,” the task force emphasized there were numerous factors at play that gave the shooter an opportunity to fire eight shots at Trump and rally attendees.

“The various failures in planning, execution, and leadership on and before July 13, 2024, and the preexisting conditions that undermined the effectiveness of the human and material assets deployed that day, coalesced to create an environment in which the former President — and everyone at the campaign event — were exposed to grave danger,” the task force wrote.

The group released its preliminary report in October, also concluding that the Butler incident was entirely “preventable.”

In the final report, one of the Secret Service’s most abject oversights revealed was its failure to secure the American Glass Research building that allowed Crooks to evade law enforcement and open fire on the crowd.

The federal agency also failed to clearly direct state and local police about who was responsible for securing the Butler venue, the task force said. A lack of adequate assets and manpower was also a concern, but it was not properly addressed. Additionally, snipers believed they were responsible for monitoring the rally and crowd, not the area outside the secure perimeter where Crooks was stationed.
