Just a quick link here to an interesting column discussing Corplan Corrections and its leader, James Parkey. Corplan has constructed numerous immigration detention centers and prisons across the country, working most often with CCA. They have built a lost of facilities on municipal bonds, and have often left small towns to foot the bill for the construction after they fail to help secure a contract to bring in prisoners - the most famous case is that of Hardin, Montana, which I've written about extensively.
But this article discusses how Corplan has been building many detention centers around the country, though not in response to a particular need for beds. The author argues, somewhat convincingly, that these beds are being constructed to give the government the ability to detain political dissidents in the case of a "national emergency." Basically, the government is building prisons to be able to silence political dissent when shit hits the fan.
That's some creepy stuff.
