The Justice Department said Wednesday it will review specialized police units around the U.S., including the Memphis Police Department’s now-disbanded SCORPION unit, after five former Memphis officers were charged with murder and aggravated assault in the beating death of Tyre Nichols, a 29-year-old Black father. That announcement came as a Shelby County judge blocked the release of 20 hours of additional video footage and internal documents related to a Memphis city investigation into Nichols’s killing.
