Peterson was arrested in Broward County after a 15-month investigation found he “refused to investigate the source of the gunshots, retreated during the active shooting while victims were being shot and directed other law enforcement who arrived on scene to remain 500 feet away from the building,”
"Scot Peterson’s inaction and the misinformation he provided to law enforcement officers had a dire impact on the children and adults who died or were injured on the third floor of the 1200 Building," Pryor said in his statement. "He stood by, leaving an unrestricted killer to spend 4 minutes and 15 seconds wandering the halls at leisure — firing close to 70 rounds and killing or injuring ten of the 34 children and educators who bore the brunt of the massacre."
They do do it sometimes. This year we had the Louisville bank shooter, the Tennessee private school shooter, the Texas outdoor mall. But I think it's not really the fact that they're cops that makes them willing to risk their lives to protect. It's more about their individual conviction and training. There are cowards and abuser who happen to be cops. There are otherwise decent (ACAB) people who happen to be cops.
