Go start one and see what happens! Do it openly. Call it the 'Well Regulated Militia of Midwestistan'. Follow the 2nd to the letter and carefully use its language and act well within its bounds. Certainly you won't come up on a terror watch list and be jailed :) My point is that yes, there is a document. No, it will not protect you until vast quantities of people all at once decide to support it. That won't happen because they don't even know what it is any more... Doubt me? Start to ask random people throughout your day if they can explain basic parts of constitutional amendments to you. Maybe 1 or 2 people out of 1000 could tell you what the 9th or 10th means. They are arguably the most important of all. Can you do so without looking them up? Write down what you think the 9th and 10th are all about before you look them up... THEN look them up. :)
