More than 100 rounds of live ammunition were fired Friday in Marjory Stoneman Douglas High School in Parkland, Florida, part of a reenactment of the 2018 Parkland mass shooting in which 17 people were killed. The reenactment was for a civil lawsuit against a former Florida sheriff’s deputy, who parents say failed to protect the victims of the shooting. CBS News national correspondent Manuel Bojorquez reports. Source
