Reenactment with live gunfire at Parkland school part of victims' lawsuit against sheriff's deputy

A reenactment using live ammunition is taking place at Marjory Stoneman Douglas High School as part of a lawsuit against the former deputy Scot Peterson.
Peterson is accused of failing to confront the gunman during the 2018 shooting that left 17 people dead.
Ballistics experts will fire shots from the same spots the gunman did to determine what Peterson heard during the attack.
Some community members and victims' families support the reenactment as necessary, while others believe it unnecessarily re-traumatizes the community.
After the reenactment, the school building where the shooting occurred will be demolished.
