I believe that was relied on a bit too much. It was much more restrictive on this issue, and it's clear that the RKBA protected by the second amendment, while related to that of the English Bill of Rights, is not the same thing, being much broader and allowing for virtual no restrictions and was passed for somewhat different reasons. At least someone, Gura I think did mention Story's edition of Blackstone where this was made perfectly clear. Of course that was in several of the Amici briefs as well, so I'm sure Justice Thomas will expand upon that point in chambers
