Whenever there is a shooting and the shooter uses a high capacity magazine the gun haters out there all circle the fire of restriction, if not outright elimination, of "high capacity magazines."

They chant and fan the flames of gun control politicians and citizens who foolishly believe that it will stop bad guys from shooting good guys.  Sensible people know that bad guys will always find a way to possess guns.

Regardless, one of the standard lines of attack is that "the Founders could not have foreseen such weapons with the capacity to deliver so many projectiles!" or words to that effect.  So, for all doubters I present...the Girardoni Air gun, circa 1780.
