Interesting that a Canadian provided the answer.

I knew it, but most Americans only think they know the Constitution -- like the guy who ask me where it said "life, liberty and the pursuit of happiness." I had to give him the entire Constitution AND the Declaration of Independence, and even after he read them I don't think that he was convinced.

Without looking it up, do you know the Fourth Amendment? The Fifth (hint: the Fifth provides constitutional justification for capital punishment)?
