An armed school deputy rushed to the Florida high school building where terrified students ran from a killer with an assault rifle, but then sat outside for about four minutes and never went inside.
The school resource deputy for Marjory Stoneman Douglas High School, Scot Peterson, was under investigation for his response to the shooting but then decided to resign his post, Broward County Sheriff Scott Israel said Thursday.
In Washington, President Trump said Friday that Peterson was either a "coward" or froze under pressure.
"He’s trained his whole life ... but when it came time to get in there and do something, he didn’t have the courage or something happened," Trump told reporters. "He certainly did a poor job.”
He said it was a case where the officer "didn't react properly under pressure or (was) a coward."
He doubled down on his depiction of the officer in a speech an hour later to the Conservative Political Action Conference.
"He didn’t turn out to be too good, I will tell you that," Trump said. "He turned out to not be good. He was not a credit to law enforcement. That I can tell you."
Two other deputies are also under investigation after a review of prior law enforcement calls involving accused gunman Nikolas Cruz spurred questions on whether the deputies followed the department's policies.
