Good luck Dianne, Heller REALLY muddies your wishes:
In regard to argument that only those arms in existence in 18th century are protected by Second Amendment, U.S. Supreme Court does not interpret constitutional rights that way; just as First Amendment protects modern forms of communications and Fourth Amendment applies to modern forms of search, Second Amendment extends, prima facie, to all instruments that constitute bearable arms, even those that were not in existence at time of founding. District of Columbia v Heller (2008, US) 128 S Ct 2783, 171 L Ed 2d 637, 21 FLW Fed S 497.
