Your case may as well rest since it is going nowhere being based upon nothing more than your distortions.
Under a strict reading of the Second I could not forbid you from entering my home with a firearm because that would "infringe" upon your right. Criminal gangs cannot be disarmed because that would "infringe" upon their right.
Terrorist bands could not be disarmed because that would "infringe" upon their rights. Classrooms could not forbid pupils bringing guns because the would "infringe" upon their rights. Courtroom could not prevent arms being brought in by spectators because that would "infringe" upon their rights. Drunks or drug addicts could not be disarmed because of the "infringement" of their rights.
If even a 1/4 of the passengers on 9/11 had been carrying personal arms on that day, New York would still have it's old skyline and 3000 people wouldn't have lost their lives.
On any given day, a random shooting happens, how many fewer would have died had they had the MEANS TO FIGHT BACK.
It is attitudes like yours that kill so many people. Mine wants them to have the option to not be a victim.
