TLDR:

The reenactment is part of a lawsuit by the victims’ families and the wounded that accuses the Broward County deputy assigned to the school, Scot Peterson, of failing in his duty to protect them and their loved ones. Peterson, who was acquitted at a criminal trial in June, has said that because of echoes he could not pinpoint the shooter’s location.

David Brill, the attorney overseeing the reenactment on behalf of the families, did not return a call from The Associated Press seeking comment Friday. He told the South Florida Sun-Sentinel that 49 rounds were fired Friday and that the test showed Peterson would have heard the shots and known their location.

What's the point of the reenactment? Peterson was a coward, that's clear, and the court already gave him a pass for being a coward, so why even pretend to care and do tests and reenactments
