Gunfire erupted again at Parkland’s Marjory Stoneman Douglas High School on Friday as part of a reenactment by ballistics experts of the 2018 massacre that left 14 students and three staff members dead. The reenactment is part of a lawsuit by the victims’ families and the wounded that accuses the Broward County deputy assigned to the school of failing in his duty to protect them and their loved ones. Reporters gathered outside heard shots just before noon, not long after nine members of Congress toured the blood-stained and bullet-pocked halls of the three-story classroom building where Nikolas Cruz carried out his six-minute attack on Valentine's Day 2018. The building was kept standing behind a locked chain-link fence to serve as evidence during Cruz's trial last year.
