>The Geneva convention on the treatment of prisoners of war would be a good place to start. Certainly it should be applied to prisoners that are taken when we go to war (eg. Afghanistan). A big problem with it may be that is somewhat out of date in reference to precice procedures relating to non-state based organisations (eg. Al-Qaeda) but I would imagine that it should not be beyond the wit of the legals to take the principles of the Geneva convention and apply them in the modern context.

Here is what our State Department has to say about it:

I am certainly not an expert on the Geneva Convention, but if we are not abiding by it, I would like to know.
