When police arrived on the scene of the Parkland, Florida shooting last week, they were confused by an apparent tape delay on security cameras at the high school.
The delay made it seem like shooter Nikolas Cruz was still on campus, although he had actually left on foot minutes earlier.
Police were also stymied by several other logistical issues, including poor radio transmission.
The Coral Springs Police Department maintains the tape delay did not affect the overall police response to the shooter and injured victims.
