But one suggestion I would put forth is not copy the bill of rights verbatum. Change a few words here and there, eg first amendment clarify freedom OF religion, not freedom FROM religion; and the second amendment, place with emphasis the phrase INDIVIDUAL RIGHT to keep and bear arms, with language preventing the kind of crap we see today, eg "assualt weapon bans."
I hear you but isn’t the problem more one of intent than words? For instance the fruitcakes who want to ban guns would say that an amendment guaranteeing an “individual” right to bear arms means that two or more cannot bear arms together or something equally silly. They always look for some way to twist the language and they claim that what IS written IMPLIES something else that is NOT WRITTEN but which they DESIRE.
