The financial mess in the Dallas school system cost 415 teachers their jobs this week, the local press reported. The front office was still trying to work out student schedules and other logistics on Friday, which was a regularly scheduled half-day for students. Meanwhile, the schools' internal anti-corruption unit has been downsized by 50 percent, the Dallas Morning News said today -- an ironic twist, given that the school district is in such dire straits because of an $84 million shortfall being blamed on human error.
