In the southwest corner of Phoenix, Arizona, a large neon vacancy sign hanging from a watchtower looms over the Maricopa County jail complex, home to the infamous "tent city" ? a facility as notorious as the tough guy Sheriff Joe Arpaio who makes it his business to keep it full. Arpaio's methods of rounding up and detaining prisoners, and the conditions to which they are subjected once inside his jails, have been relentlessly criticized by human rights groups. Yet, there is no indication that the vacancy light at the complex will be switched off anytime soon.
