If it's an ethical, legal, advanced method in Gitmo why aren't we using it here? We could find out where Madoff/EnRon execs stashed all that money, where Jimmy Hoffa is buried, where Santa Claus lives, etc...
People are bullshitters most of the time about crap like this. Same as with the wars. People insist we should be there until the idea of having a draft (with no exception/waiver) comes comes up and then they start to stutter. People only have commitment to shit like this that doesn't affect them personally.
