Mysterious Prison Buses In The Desert

"Prison buses are driving around empty in the Tucson area. Are Wackenhut and the DHS preparing for civil unrest?

The new Wackenhut operation is shrouded in mystery. It has been running its fleet of empty prison buses night and day, apparently logging miles on a Department of Homeland Security (DHS) contract. Multiple buses can be seen driving all over town and even on remote desert back roads. Oddly, except for the driver and one escort guard seated in front, these buses are always empty."
