In the days after Hurricane Katrina, thousands of American citizens were rounded up and imprisoned at a makeshift fenced-in holding area at the city's bus station. The prison was nicknamed "Camp Greyhound." Citizens were not allowed phone calls. They were not given lawyers. Their property was confiscated, and they were held without charge. Prisoners were sometimes beaten, pepper-sprayed, and forced to sleep in the open-roofed cages on the greasy pavement that was once bus parking spots. Some went on to serve months in Louisiana prisons, only to have all charges eventually dropped.
