The armed officer on duty at the Florida school where a shooter killed 17 people never went inside to engage the gunman and has been placed under investigation, officials announced Thursday.
The school resource officer at the high school took up a position viewing the western entrance of the building that was under attack for more than four minutes, but “he never went in,” Broward County Sheriff Scott Israel said at a Thursday news conference. The shooting lasted about six minutes.

The officer, Scot Peterson, was suspended without pay and placed under investigation, then chose to resign, Israel said. When asked what Peterson should have done, Israel said the deputy should have “went in, addressed the killer, killed the killer.”
