If you didnt believe BILL CAMPBELL was a crook when he was mayor, then you werent paying attention. A puzzling jury verdict acquitted the slickster on racketeering charges. But Hizzoner still will be sporting prison scrubs for the next couple of years, because he couldnt escape the tax evasion charges. Even though Campbells high-profile trial, conviction and incarceration gave Atlanta a black eye, letting him get away with his skullduggery as he ran the city into the ground wouldve tarnished our reputation all the more. Perhaps as much as the verdict, justice was served by the courtroom revelation of the former mayor as a petty, vindictive philanderer who spent as much time playing blackjack and taking vacations on other peoples dimes as he did at City Hall. And when he gets out of the slammer, maybe he can run for mayor of Tunica, Miss.
