Here comes another of my highly educational posts. The "right to bear arms" was granted to a "well-regulated militia" so they could defend America if the federal government ever tried to turn our nation into a monarchy. When the 2nd Amendment was written, the "arms" were flintlock rifles and muskets. The musket had to be loaded with gunpowder and a lead or lead-tin-alloy musket ball. An expert musketeer could fire only three or four rounds per minute and the accuracy range was around 50 yards.
James Madison could never have foreseen that in the 21st century there would be a weapon (the AR-15) which holds 30 rounds and can fire 45 rounds per minute with an accuracy range of 600 yards. I doubt even Madison would want private citizens to own guns that can kill 2,700 people an hour.
With bated breath and a heart that is simply all aflutter, I await Mister JHDK's response.
