When the shooting started at Parkland's Marjory Stoneman Douglas High School, both students and teachers went into a mode they were prepared for after extensive training. They were told to lock the classroom door and shelter in place if the sounds of gunfire echoed in the hallways.
That is just what the students and teachers did inside that school. They hunkered down and were ready to wait for the law enforcement members to reach their classroom. That is until something else happened; the fire alarm rang.
As USA Today reports, after all the directions passed along in the various training that covered the many different crisis situations that could happen inside a school, a simple fire alarm tossed all that preparation to the wayside. Broward County school board member Donna Korn explained that the faculty, administration, and students, have undergone various levels of "active shooter training."
It appears that the accused shooter, Nicolas Cruz, who was a former student of that school, was very familiar with that training as well. The results of that training played out as soon as the sounds of gunshots were heard coming from the hallways of the school. USA Today suggests that Cruz "appears to have rendered that preparation moot with a flick of a fire alarm."
