Parkland school shooting to be reenacted with live gunfire

Ballistic experts in Parkland, Florida are firing at least 140 live rounds of bullets during a reenactment of the 2018 mass shooting at Marjory Stoneman Douglas High School. Friday's reenactment is a part of a civil lawsuit against Scot Peterson, a former sheriff's deputy who remained outside during the massacre. Peterson was acquitted of criminal charges related to the massacre, but is currently being sued in civil court.
