Closing arguments underway in trial of Florida deputy accused of failing to stop Parkland school shooter.

Prosecutors argued that Deputy Scot Peterson, a Broward County Deputy, fled to safety during the 2018 Parkland school massacre, putting his own life ahead of the children he was charged with protecting and giving the gunman time to fatally shoot several victims. Peterson is being tried for felony child neglect and other charges for the deaths and injuries on the third floor. This is the first time a U.S. law enforcement officer has been tried in connection with a school shooting.
