A total of eight deputies from the Broward Sheriffs Office heard the jarring blasts of an AR-15 rifle and failed to enter the school and confront Nikolas Cruz as he roamed the halls shooting students and staff. Cruz killed 17 people and injured another 17.
...
Two school employees did confront Cruz and they were killed. The big failure was nobody called a Code Red, which means everybody goes into a classroom and the doors are locked, which would have saved lives.
There’s more hate for the police officers than there is for the shooter.
