Are musicians owed royalties for performance of their music in torture chambers?

Canadian copyfighter Howard Knopf has suggested (presumably with tongue firmly planted in cheek) that recording artists whose music is played by torturers in Gitmo are owed performance royalties:
Leaving aside the legal niceties about whose law if any applies in that dreadful place, one can only wonder if ASCAP might not want a piece of the action. After all, it went after the Girl Guides not so long ago. And if it could try to make a buck off Girl Guides, who are nice people, why not alleged terrorists? Why should terrorists enjoy free music?
