Does anyone know if they have a legal leg to stand on with this case? Or is it just more of a symbolic lawsuit? Also, I'm very curious who chooses the music for torture/what goes into their decision.
Probably symbolic. Although it would be funny to see the military marshall actual defenses to copyright infringement. Maybe Cuban copyright law doesn't prohibit what they're doing. If Guantanamo is considered to be under American jurisdiction, maybe they have licenses from the performing rights organization[s] that administer the band's catalog. Or maybe they'll argue that the torture cells are not considered open to the public, and therefore don't require licenses.
But most likely they'll just ignore it, because it's America, and when the fuck have we cared what other countries think?
