OKLAHOMA CITY (KOKH) — The Oklahoma Second Amendment Association said Tuesday that it supports those who plan to march armed in Tulsa for the 100th anniversary. OK2A said, when Oklahoma became a state in 1907, Second Amendment rights were ignored and it was illegal for a peaceful person to carry a knife, pistol, rifle, or shotgun for self-defense. This led to the Tulsa Race Massacre, OK2A said, adding, "citizens that were attacked should have never hesitated to defend themselves or their property."
