Every decision that is made rewrites the Constitution to some extent because it is dealing with a question the framers did not anticipate.
The constitution was never meant to be the final word. It is a set of basic principles that provide the foundation of American law. Just as church tradition/Talmudic interpretation expands upon scripture, so legal precedent expands upon the constitution in response to changing situations.
I despair of the number of people who know the answer and don't want to be confused by intellectual arguments.
