Remember: The government's plan is to confiscate your rights that are protected by your right to bear arms to stand against their tyranny.
The only way their tyranny can grow beyond its current borders is to strip Americans of their rights to bear killing weapons that they are afraid of.
My advice? Buy a non-lethal and have a plan in place for when this eventually happens to all of us (except if you're a gangbanger in Chicago, they'll not come for your guns - gotta strip legal gun owners first as a pretext for the death squads)
