Armed school cop did not confront gunman

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, police have announced.
The Valentine's Day shooting at Majory Stoneman Douglas High School by a gunman armed with an AR-15 style assault rifle reignited national debate over gun laws and school safety.
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 4 minutes, but "he never went in," Broward County Sheriff Scott Israel said at a news conference.
The officer, Scot Peterson, was suspended without pay and placed under investigation, then chose to resign, Israel said.
