Leaders must ensure that those they deploy are ready to do their duty. The scapegoating of Deputy Scot Peterson by Broward County prosecutors and Broward County Sheriff Scott Israel proves that hasn’t happened in Florida.

On Feb. 14, 2018, Nikolas Cruz entered Marjory Stoneman Douglas High School in Parkland, Fla. He then murdered 17 innocents before being arrested. But this week, Peterson, who had been assigned to the school, was charged with offenses in relation to his failure to intercept Cruz.
