But it doesn't usually include swords, which a lightsaber is closer to a sword than "arms" which is typically defined as a firearm these days. I guess it depends how definitions change by the time they come to fruition.
SINCE THE SECOND AMENDMENT PROTECTS THE RIGHT TO BEAR ARMS "THAT WERE NOT IN EXISTENCE AT THE TIME"; WILL IT ALSO PROTECT MY RIGHT TO KEEP A LIGHTSABER?
