Obviously, you are unable to learn anything new.
Re: your link + the comment: "A long list of gangbangers, drug dealers, and armed robbers. Not one Constitutionalist arguing on behalf of the second amendment and sawed off shotguns. Pretty compelling to me...
Why do you suppose there's no lawfull owners short barrels in your list that committed crimes with the guns? Why do you suppose that since 1934, that only one crime was committed with a legally owned machine gun in the US, and the criminal that owned the machine gun and committed the crimes, including murder, was a cop wearing brass? A cop that later committed suicide?
Your post makes little sense. Somehow this doesn't surprise me.
Let me get my magic decoder ring...Standby.
