First off, contrary to what you and Richard Nixon think, just because the president says it is not illegal that does not make it so. Using your logic, our president could surround himself with a bunch of yes men who would write a legal opinion that searches of trailer homes are not covered by the fourth amendment because they have axles and therefore can be moved before a warrant could issue, and that would be the new legal view. The reason we have three branches of government is because we don't want one branch making rules then saying the rules they made are legal. Other people get to decide that.
As to my reference to Germany, you were talking about ex post facto laws and the War Crimes trials in Germany are in many cases prime examples of that. I was not comparing Hitler to Bush but the claim that you were making about ex post facto laws. But I don't expect you to get it.
And finally, sorry to hear that your mom is dead. Why don't you pick some other member of your family for waterboarding and then we can tell them it is not torture
