The assassination attempt on Donald Trump exposed critical vulnerabilities in security protocols designed to protect high-profile figures.
Multiple lapses allowed Thomas Crooks to breach defenses and position himself for the attack. Crooks used a drone for reconnaissance, taking advantage of a delayed deployment of the Secret Service’s drone-detection system, which left the airspace around the venue unsecured and allowed him to map the area without detection.
Crooks gained access to a rooftop overlooking the stage, highlighting deficiencies in both pre-event security assessments and active monitoring. Despite multiple security checkpoints, he managed to carry an AR-15-style rifle, explosives, and reconnaissance equipment to this location, pointing to gaps in the screening process.
Due to personnel shortages, the rooftop was left unguarded, leaving an unobstructed line of sight to the stage. While police snipers were stationed inside the building, no personnel were assigned to cover the rooftop area, with Secret Service Director Kimberly Cheatle pointing to safety concerns with the sloped roofs. Additionally, requests for added security were reportedly denied.
Communication failures further complicated the response. Local snipers observed Crooks’ suspicious behavior for over an hour but did not relay their observations to the Secret Service. Key details about his position were not shared through the Secret Service radio network, preventing timely intervention.
Moreover, coordination challenges among the 155 law enforcement personnel—including Secret Service agents and SWAT teams—left several coverage gaps, and reports from eyewitnesses of suspicious activity went unaddressed.
In the days leading up to the incident, Crooks purchased over 50 rounds of ammunition and a ladder — activities that went unnoticed. Just hours before the event, Crooks’ parents reported him missing and voiced concerns, raising further questions about missed warning signs.
