Police union won’t defend Florida’s 'coward' sheriff’s deputy, but not for the reason you’d think

When school shooting suspect Nikolas Cruz unloaded rounds from his AR-15 into students, teachers and faculty members at Marjory Stoneman Douglas High School last month, sheriff’s deputy Scot Peterson, who was on duty as the school’s resource officer, failed to enter the building as 17 people died — but that’s not why the police union representing him won’t be defending.
