You put too much stock in lawyers. Klinton was a lawyer. Some source of authority, huh?
If you are going to employ argumentum ad verecundiam - an inherently weak approach as it is though one you nevertheless seem to enjoy - the very least you can do and the only way you can give your appeal the shadow of legitimacy is to ensure that your chosen expert is credentialed in his field. Otherwise your quote about constitutional law is no more validated by its source than Sean Penn's opinion on global warming.
