That's the main reason I have zero tolerance for left wingers who cry about Guantanamo and whatnot. I was there. Water boarding is too good for those animals.
The problem is that terrorist attacks like that are often sponsored by secret services of different countries. The ones who end up water boarded in places like Guantanamo are always "little fishes", while the big ones continue to sit in their offices and enjoy the life. I personally would have enjoyed all those generals and colonels who exploit terrorism to undergo the same treatment.
