What If the US did what so many so called human rights orgs want US to do? What if they released all the prisoners (remember, these are people who have sworn they want to destroy America and are highly suspected of doing things to actively achieve that end).
What if some of those released come back at US 5 or 10 years from now.
What if they become responsible for the killing of 10,000 Americans or 100,000? What if they hooked up with someone who has the bomb and manged to kill close to a 1,000,000 Americans?
We already know they want to................
What will those Americans who are screaming to have these prisoners released say then:
1. "Oh, well....can't be afraid all the time...can't live in a bubble"
2. "My God!......who is responsible for this-------can't be me and my calls for their freedom". "Dam Bush, he did this on purpose to give us a reason to attack (fill in country here)".
3. "It is better to uphold ideals and lose a few million lives then to bend those ideals and lose who we are....when we do that the enemy really wins...blah blah blah"--------
yeah right....I am sure the enemy is cheering in the streets when we "bend" our ideals and come at them with everything we got vs when they kill each and every last one of us 
--------------------------
THEY WANT TO KILL US ALL..........doesn't anybody understand that?
