To help with the fear that the government could take away legal guns, the following would need to occur. 1) Repeal the 2nd Amendment 2) Reverse DC -v- Heller 3) Repeal the Posse Comitatus Act ( It would require the military to enforce confiscation )
Posse comitatus is the common-law or statute law authority of a county sheriff or other law officer to conscript any able-bodied man to assist him in keeping the peace or to pursue and arrest a felon, similar to the concept of the "hue and cry". Originally found in English common law, it is generally obsolete; however, it survives in the United States, where it is the law enforcement equivalent of summoning the militia for military purposes.
Idaho Opens the Door to Martial Law & Gun Confiscation – Nullification of Posse Comitatus Act. The National Guard was meant to help in times of emergency, not act as a civilian military force at the beck and call of politicians who are more than willing to violate our constitutional rights. Furthering the deployment of the National Guard other than for legitimate emergencies is a violation of our rights.
