One thing you have to understand, though, is that these detainees in places like Gitmo have a very unusual legal status under both U.S. and international law. They aren’t U.S. citizens and they haven’t been captured on U.S. soil...
It’s quite probable that some of the info we’ve gotten from some of these terrorist combatants has prevented a few attacks on your soil, too. Your simple-minded foolishness is only superceded by your blind ignorance.
