@FreeDuck,
I never nor will I ever consider waterboarding to be torture. Nor is slapping or sleep deprivation torture in my opinion. Nor do I think waterboarding should be used in every circumstance. It is an aggressive form of interrogation and should be use only in extreme circumstances.
Since these prisoners are not American citizens, they are not entitled to any rights granted under the US Constitution.
Therefore, to argue that waterboarding be used in law enforcement is a false argument.
