Torture and Copyright

It's no secret that some Guantanamo Bay detainees are subjected to sessions of disorientingly loud rock music as a way to break their spirits. The question remains whether torture qualifies as a fair use under the Copyright Act. Could an artist sue for infringement if they disapprove of their music being used this way? Should they be paid royalties by the interrogators?

If I were a law professor, I would surely give my students this question on an exam and watch them cry.
