The families of the defendants are elated as the LAPD quartet go free. My boss at the Metropolitan News-Enterprise, Lowell Forte, who was once a small-town prosecutor, makes a lawyer joke about the legal strategy of Sergeant Stacey Koon, the senior LAPD officer at the beating scene. Koon tried to distance himself from the men doing the pummeling. Lowell calls it the “reverse Nuremberg defense.” As in: “I was only giving orders.”I feel unaccountably uncomfortable — not really frightened, but nervous — being downtown after the verdict, and I instinctively file my now-forgotten copy and leave work early. Why does it seem as though it’s already getting dark outside City Hall, two hours before sunset? Who are all those loud people gathering in loose clumps around Parker Center and what are they doing there?
