Did you ever wonder why the White House set up the Guantánamo prison and why they operate it the way they do? If any of the prisoners have any real connection with terrorism, then certainly it would be easy to prosecute them in a normal civil or military court. In today's climate of fear, any judge or jury would just love to get the chance to "hit back" at terrorism by handing down a stiff verdict. They probably would even accept thin evidence.

My own suspicion is that there are several other reasons for Guantánamo . . . I imagine there are two immediate reasons for the secrecy and the shredding of judicial protections. First, most of the prisoners are probably not terrorists at all; they were rounded up simply to boost the numbers. The secrecy and isolation permit the treacherous charade to be continued without interference or outside knowledge. Second, there are probably a few prisoners who really were involved in the Al Qeada network. Those must be kept isolated because of the stories they could tell about CIA connections with Al Qeada leading right up to 9-11.

But I believe the underlying fundamental reason for Guantánamo, and its flagrant brutality, is to establish a precedent to enable more concentration camps in the USA
