Part 4/9:
Failure to Secure Areas: The area from which the shooter, Thomas Crooks, fired was not properly secured. Secret Service agents erroneously believed that state and local law enforcement were responsible for securing that section, failing to verify this arrangement before and during the rally.
Communications Breakdown: Critical communication failures occurred, including the inability for agents in the field to relay vital information regarding the shooter. There was a lack of a unified communication system in place, leading to confusion during the crisis.
