Scot Peterson trial begins for not confronting Parkland gunman.

The trial of former Broward County Deputy Scot Peterson, accused of not preventing some of the Parkland school shooting murders, began with wildly divergent opening statements from the prosecution and defense. Peterson is charged with seven counts of felony child neglect and three counts of misdemeanor culpable negligence. If convicted, he could get a prison sentence of nearly a century and lose his $104,000 annual pension. The prosecution must convince jurors that Peterson knew Cruz was shooting inside the building and that his actions and inaction exposed the victims to harm.
