I am all for the Second Amendment as it is written – to include the part about the “Well Regulated Militia” (whatever that is), just so long as the application is limited to the technology of the time that it was written. That is to say, muzzle-loaded, single-shot weapons.
There is no way the authors of the Constitution could possibly have envisioned the weaponry of today. They are clearly outside the scope of the Second Amendment and should be regulated and/or banned as necessary to protect the population.
Lest this seem extreme, machine guns, cannons, bazookas, etc., are banned. Where is the line drawn?
