Rapid fire weapons and high capacity magazines were not envisioned when the constitution was written

and therefore should not be protected by the Second Amendment. That's a favorite argument by the gun grabbers. If the founders could not imagine the destructive power of an AR-15 then they could not have intended for citizens to have a right to possess such weapons.

Ok, if you want to play that game then the founders had no idea we would one day have worldwide televison and internet with instant news. They had snail mail and printing presses. "Freedom of the Press" literally meant freedom with a press. Maybe the First Amendment doesn't apply to MSNBC and the Huffington Post.
