Last December the school board brushed aside a proposal by its maverick member, Marta Perez, to create an ethics commission that would act as a watchdog over the district. Why? Millions squandered on questionable land purchases. Fortunes spent to settle sexual-harassment lawsuits. Administrators with diploma-mill degrees. Overcrowded classrooms. Underpaid teachers. Unwelcome parents. But in rejecting the measure, Perez's colleagues argued that they didn't need an ethics commission because there weren't any problems. Now, that takes chutzpah.
