I have to disagree with you on the Second Amendment. It is very clear on the meaning. The "militia clause" is not a modifier or limiter on the right. The subject of the sentence, "the right to keep and bear arms", is clearly meant for the people. The "people" clearly is the individual.
You might want to find a copy of J. Neil Schulman's "Stopping Power". It has a very good section on the sentence structure of the Second Amendment.
What a coincidence (actually, it's probably not). The article I just linked to is by Schulman, called "The Unabridged Second Amendment."
