Scot Peterson on Trial for Inaction During Parkland Shooting.

Former sheriff's deputy Scot Peterson has gone on trial for failing to protect students during the 2018 Parkland school shooting in Florida. Peterson, who was the on-duty police officer during the attack, faces 11 charges, including seven of felony child neglect, three of culpable negligence, and one of perjury. Prosecutors allege that Peterson failed to follow his active-shooter training and did not enter the building as shots were fired, endangering students. Peterson maintains he thought the shots were coming from outside and that he would have confronted the attacker had he known.
