That did not deter the Federal Judiciary from making a large class of different weapons illegal under the specious claim that they were not "military" in nature in the Miller decision. Preposterously, the Court claimed in Miller that a sawed-off shotgun had no military use, and therefore could not be a weapon employed by a militia. Never mind that a standing army and a militia are two different things, nor that a sawed-off shotgun was, even at the time of Miller of general use in the US ARMY. [In fact, for my father--a BAR gunner in WWII--a sawed-off double barrel eight gauge was his side-arm of choice, which he much preferred to the 45-caliber pistol]
As you know, Miller was a poor precedent, because Miller himself (a small-time gangster) had been killed by the time the case reached the Supremes. No one was particularly interested in standing up for Miller's rights, and no one foresaw the damage this decision has done and continues to do every day.
However, the Left's preoccupation with "Militia" in the 2A can be worked to their great disadvantage, by pursuing the line of reasoning I gave.
We have lost on the short-barreled shotgun, and I doubt we will get it back in the near future. But it seems to me that the AWB, magazine limits, and select-fire rifles may be back on the table if we get the militia emphasized. Plus there are a large number of what the BATF wants to call "destructive devices" that are currently in use by our armed forces, which should be available to a militia.
