Behind Bars: The World's Toughest Prisons

The Dallas County Jail in Texas - a mega-jail with room for 7,100 inmates, where everyone from small-time criminals to serial killers wait for their day in court. Mass processing of new inmates occurs on a daily basis: Up to 300 new arrivals per day are registered by prison staff. Those who enter must be aware of the turf wars. Gang warfare and turf battles are even more critical on the inside where there is less real estate to divide up. Gang warfare is even more relentless within these prison walls.
