I don't mean to imply that you're wrong (afaik, you're actually correct here), but I do want to point out that the interpretation and legal enforcement of the constitution is supposed to be done by the Supreme Court (and, to a somewhat lesser extent, the entire judiciary branch). I'm not sure to what extent the SC can pass judgments / make rulings without being prompted by a lawsuit, though at the very least it seems to me that the ACLU at least keeps the important stuff on their radar ;)
