The Third Geneva Convention, of course, contains a large number of standards, not all of which would necessarily apply to a detainee taken in this particular conflict.
The primary one that is important, of course, is the humane treatment provision--i.e., the individual is entitled to his physical integrity and is not to be tortured. The primary one that is of most interest as well is the right of access to the International Committee of the Red Cross. That would not normally be granted in cases of unprivileged belligerence; it's a privilege in that particular case.
The Third Geneva Convention also contains a number of other privileges that are given to.... If you have seen movies of the Second World War, you'll have seen the way prisoners would be grouped in various detention camps. These are not the kinds of rights we're talking about. We're talking about the prima facie standards of treatments, namely humane treatment and right of access. Those are provided by the Third Geneva Convention.
