Two decades after Columbine and five years after Sandy Hook, educators and police still weren’t ready for Parkland.
Failures by the Broward County Sheriff’s Office and school district cost children their lives at Marjory Stoneman Douglas High School.
A gunman with an AR-15 fired the bullets, but a series of blunders, bad policies, sketchy training and poor leadership helped him succeed. Information reported over 10 months by the South Florida Sun Sentinel reveals 58 minutes of chaos on campus marked by no one taking charge, deputies dawdling, false information spreading, communications paralyzed and children stranded with nowhere to hide.
To be sure, a number of teachers and police officers performed heroically. But an examination of the day’s events reveals that the Sheriff’s Office and school district were unprepared for the crisis.
