A former Broward County Sheriff's deputy who didn't rush into Marjory Stoneman Douglas High School as a gunman killed 17 students and staff members is scheduled to testify this week before the commission investigating the massacre.
Scot Peterson, 55, could also refuse to testify by citing his Fifth Amendment right against self-incrimination.
Peterson is scheduled to testify Wednesday during the second day of this month's three-day hearing of the Marjory Stoneman Douglas High School Public Safety Commission.
Peterson, then the school's resource officer, is scheduled to testify about security camera video that shows him hurrying to the three-story freshman building, drawing his handgun but then remaining outside even though Broward County sheriff's officials say his training taught him to charge in and shoot the gunman.
President Donald Trump and others have called him a coward for not doing so, something he has vehemently denied. He will also be given a chance to discuss that training and whether it was adequate.
If Peterson testifies, he is sure to face hostile inquisitors.
