Excellent comments.
Our Framers were correct in their fear that if some rights were enumerated, others would be excluded.
Hell, even if they ARE enumerated they can be excluded: look at the 2nd Amendment.
According to a plain-text reading of the Second Amendment the ONLY possible gun regulation would be that of ensuring a “regular” militia; something along the lines of “Every Citizen of able body must possess a .45 ACP semi-automatic handgun AND/OR a .30-06 rifle.” or something similar thereunto.
