The Secret Service missed 102 radio transmissions concerning Thomas Crooks, who was armed with a long gun on a nearby roof, before he fired shots at a campaign rally for former President Donald Trump, according to a Department of Homeland Security Office of Inspector General report. These missed communications occurred prior to the July 13 incident in Butler, Pennsylvania, where Trump was the target of an assassination attempt. Crooks died at the scene after being shot by a Secret Service agent when he attempted to breach a security perimeter. The report indicates that the agency had multiple opportunities to intercept Crooks before he reached the roof and opened fire, thereby preventing the incident. The watchdog's findings highlight significant gaps in the Secret Service's operational security protocols and communication procedures during the event.
