2 hour special - Comparing a California prison to Harvard seems a stretch. But, according to a new Ted Koppel documentary, it costs about as much to contain one prisoner for a year as does an academic year's tuition, meals and housing at Harvard. And neither has vacancies. Built to accommodate no more than 100,000 inmates, California's prison system now holds 173,000, reports Koppel, which potentially could lead to a court-mandated release of inmates to ease the crush. How did the situation reach this extreme? That's what Koppel explores in his new documentary, "Breaking Point." This latest "Koppel on Discovery" edition premieres 9 p.m. Sunday on Discovery Channel.
