ElvisL1ves, I think it’s a little oversimplistic to say “The Supreme Court has spoken” and to dismiss any protestations as futile ranting akin to the specious arguments tax protesters use to claim the IRS is illegal.
For starters, Supreme Court decisions are not immutable: Brown vs. Board of Education flatly overturned the previous doctrine of “separate but equal”, and it didn’t requre a constitutional amendment to do so. Rather, it brought a case to court that pointed out that the “equal” part was so routinely violated that the previous standard could never effectively be upheld. Supreme Court decisions may be the law of the land, but that doesn’t mean that they are logically consistant or weren’t merely legalistic rationalizations for an Ad Hoc position the court majority took. Many people believe the logic of Miller to be incorrect, and they ARE doing something about it: they’re bringing a case to the Supreme Court that will finally explicitly state either that the government can regulate private gun possession out of existence, or it cannot. If the SC does rule that DC can effectively ban private firearms, then we may indeed see a push for a constitutional amendment to rectify that.
Secondly, there seems to be a bit of a logical leap that we would like clarified: in Miller, the court ruled that the 2nd Amendment does not make federal laws banning some types of firearms unconstitutional. Accepting that as a given for the moment, how do you leap to the conclusion “and therefore, no one who isn’t a National Guard member should have a gun”? Miller brings up the word “militia” because the appeal was explicitly based on the 2nd Amendment, which uses the term. But the ruling says nothing about militia membership; it only addresses whether the firearm in question could reasonably be considered to be a military weapon.
Thirdly, there is disagreement over exactly what the letter of Miller means. Proponents of gun control hold that in the Miller case, the Supreme Court explicitly stated that the 2nd Amendment makes gun possession dependent on, and subordinate to, enrollment in a government-organized militia such as the National Guard. That the purpose of the 2nd is subordinate to that goal, and therefore all other considerations that don’t directly support the goal can be ignored. Yet opponents of gun bans hold that that interpretation of Miller is overbroad, and that nothing in Miller explicitly supports that supposition.
Fourthly, there is the whole can of worms over the fundamental definition of the terms “militia” and “well-regulated”. Proponents of private gun rights point out multiple writings by the Framers that would seem on the face of it to contradict the “National Guard” theory of the “well-regulated miliita” clause of the 2nd. Again, Miller does not define either term, or say what is and what is not a militia under the 2nd; it merely addresses the subject of certain classes of weapons- specifically, jury-rigged weapons designed primarily for committing crimes, with little or no military utility.
Lastly, the fact that there is so much controversy over the 2nd Amendment and the rulings and court decisions concerning it, is ample proof that there is legitimate doubt about the meaning and interpretation of the provisions. Debates over such meanings and interpretations are relevent, because otherwise the original intent of a written statute could by a slippery-slope process get interpreted out of existence. As I sarcastically said upthread “So apparently, the 2nd Amendment means ‘You have the right to be drafted and have the army issue you a weapon’”.
