Gitmo Bay

I can't understand why there is such a controversy about where to put the detainees from Guantanamo Bay. Why must we put those people ANYWHERE??? Why don't they just unlock the doors and let them go. They're in Cuba, for goodness sake. I'm not even sure they will try to go anywhere anyway, but if they do leave, they dare not try to harm any of our soldiers there as that would provide a reason for the soldiers to shoot them. If they go on into Cuba, the Cubans will probably shoot them. If they want to leave Cuba, let them get on a raft and try to make it to the U.S.
