A police officer who was on duty at a Florida high school and did nothing to stop gunman Nikolas Cruz when he started his massacre has been suspended.
Deputy Scot Peterson, who was armed with a handgun, didn't follow police procedure and immediately confront Cruz when he started his rampage killing 17 people with an AR-15 assault rifle, according to the Broward County Sheriff's department.
Instead he took cover at Marjory Stoneman Douglas High School for upwards of four minutes and 'never went in ', according to Sheriff Scott Israel who said Peterson's actions left him 'Sick to my stomach. There are no words.'
Israel added that the school resources officer should have have 'gone in, addressed the killer and killed the killer.'
The revelations come amid an intensifying debate about how to deal with school shootings, with many including President Trump and the NRA arguing that armed guards and teachers can 'instantly' take down gunmen.
