Seems to me that many are missing the bigger picture here.

Rather than use odd music (if some of what they use can be called music) as a means of collecting important information in the roundup of international terrorists, should we just turn them all loose and wait until they strike other innocent peoples causing high fatality rates? (would it be more acceptable after a major suicide bombing to be able to say, 'Instead of playing Barney to him for hours on end we released him so he could do this because it seemed more humane'?)

If playing some Barney or Metalica noise for a period of time will save hundreds or even thousands of lives, what is wrong with it? It's not like using medieval tortures or reviving the Spanish Inquisitions.

I think a lot of the bleeding hearts need to get their priorities sorted out here!!
