Corporate 2nd amendment rights

"The Deacons’ nonprofit exercised its Second Amendment rights by conducting nighttime patrols of black neighborhoods. The agents of the corporation carried .38 caliber revolvers and M-1 rifles with their standard 15 and 30-round magazines. Deacons chapters proliferated to protect community organizers. The Deacons even provided armed security for the largest civil-rights march in Mississippi history, the “Meredith March Against Fear” in June 1966."
