We know from experience that history repeats itself. Can anybody say, “FISA!”?
We might note that Magna Carta was, in succeeding centuries, a propaganda document, not a legal one. King John repudiated it, and then died. Later kings granted many of its rights, but only as a gift, not as something that was binding on the king. So it was no longer a legal document. That probably was one of the things that made it good propaganda. There had not been centuries of clever fellows twisting it and making all sorts of exceptions.
