The real reason the Second Amendment was ratified, and why it says "State" instead of "Country" #the Framers knew the difference - see the 10th Amendment#, was to preserve the slave patrol militias in the southern states, which was necessary to get Virginia's vote. Founders Patrick Henry, George Mason, and James Madison were totally clear on that . . . and we all should be too . . .

. . . Little did Madison realize that one day in the future weapons-manufacturing corporations, newly defined as "persons" by a Supreme Court some have called dysfunctional, would use his slave patrol militia amendment to protect their "right" to manufacture and sell assault weapons used to murder schoolchildren.
