The Parkland school resource officer who did nothing as a teenage gunman murdered students and teachers appeared in court on Wednesday after being charged with neglect. 

Scot Peterson was stony-faced as he appeared via video link to a court in Fort Lauderdale, Florida, from the Broward County Jail. 

He was charged on Tuesday with failing to protect the 17 students and teachers who were killed by Nikolas Cruz on Valentine's Day 2018 at Marjory Stoneman Douglas High School. 

On Wednesday, Peterson's lawyer tried to have the charges dismissed and also asked for his bond to be reduced. The judge denied both requests. 

Peterson, 56, was arrested on Tuesday on 11 charges including child neglect, culpable negligence and perjury. If convicted, he faces a potential prison sentence of nearly 100 years.
