Unreleased police radio transmissions have revealed significant communication failures by the Secret Service during the attempted assassination of Donald Trump at a rally in Pennsylvania on July 13. Despite being flagged as suspicious, the would-be assassin, Thomas Matthew Crooks, managed to lose law enforcement for over 20 minutes and fired an AR-15, killing one attendee and injuring others. Critical messages about Crooks' location were not received by the Secret Service because they were stationed 300 yards away with no direct communication link to local police. The chaotic response was exacerbated by poor cellular service, leading to delays in information relayed through personal cellphones. The incident has prompted criticism of the Secret Service, culminating in the resignation of its director, Kimberly Cheatle. These communication issues highlight a concerning breakdown in security protocols for protecting high-profile individuals.
