Nor is there anything, anywhere in the constitution giving you the right to own grenades, rocket launchers, c-4, nuclear explosives, or fighter aircraft...but we as a society would likely frown upon such a thing. We are also faced with the fact these weapons not only did not exist...but were not imagined as possible at the time.
It is unlikely any "Well Regulated Militia" would be allowed to be armed with such. Unless you fall into the crowd expecting (Or Preparing For) the upcoming military takeover of the United States there is no logical reason to be armed with such weapons.
And...to be honest, if you are the mental health aspect of the actions will likely find you anyway.
