The US proposes to put an immigration prison in Guantanamo. This is a bad thing to do, and not only for symbolic reasons. The reason Dubya put the torture center and prison there was to take advantage of a legal loophole which reduced the rights that prisoners could claim there.

The same will apply to any immigrants sent there.

We have already seen difficulty in making sure that all unauthorized immigrants get their legal rights even when imprisoned in the US itself. No immigration prison should be in Guantanamo.

Using private contractors to run an immigration prison is also wrong, for similar reasons.
