I've been doing some detailed readings of Heller to see how it might apply to current laws in my state. Of interest is their analysis of the phrase "keep and bear arms". I was curious as to whether or not they would view "keep and bear" as one right or two.
The court concluded: "Putting all of
these textual elements together, we find that they guarantee
the individual right to possess and carry weapons in case of confrontation."
By my reading, this renders as unconstitutional any state laws that prohibit the open carry of handguns, such as the City and County of Denver. They specifically said in the ruling that it didn't apply to conceal carry, but clearly DO apply it to open carry.
