Behind Bars

Tent City Jail - a prison in the desert of Arizona, USA, where tents instead of cells make up prison housing. Harassment is part of the deal; male prisoners are required to wear pink underwear, and while the same monotonous meal is served daily, the food channel is on, taunting the prisoners. Prison work troops are chained together, a pratice dating back hundreds of years.

Welcome to Antanimora Prison in Madagascar. A prison in the middle of the capital Antananarivo and bursting at the seams. Originally built for 800 prisoners, the complex houses more than 3,000 prisoners. They sleep crammed together, body against body, some on the bare floor. Only a few have a chance of getting better conditions.

A prison with guards on the outside but not on the inside because they fear for their lives. On the inside, the prisoners are in control: murderers, violent offenders, drug bosses. This is the prison city of San Pedro in La Paz, Bolivia, where the inmates rule and anarchy prevails. Only the strongest survive this lawless place, and they rule over the weak.

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 gang warfare and turf battles that happen inside.

Sofia Central Prison - a Bulgarian detention center, crumbling foundations and fit for demolition - derelict conditions too much to ask of anyone - even a criminal. Multi-prisoner cells, bunks stacked three stories high as well as a large count of isolation cells where prisoners spend 23 hours a day behind rusty bars, with nothing to do, vegetating their days away.

The Miami-Dade County Jail and the Miami Dade Boot Camp - the two toughest divisions of the Miami Dade prison complex but they couldn't be more different. Boot camp doesn't give its participants a minute to themselves, but the inmates in prison have nothing but time to themselves. Two extremes, united in one world.
