Newton had discovered, during classes at San Francisco Law School, that California law allowed people to carry guns in public so long as they were visible, and not pointed at anyone in a threatening way.In February of 1967, Oakland police officers stopped a car carrying Newton, Seale, and several other Panthers with rifles and handguns. When one officer asked to see one of the guns, Newton refused. “I don’t have to give you anything but my identification, name, and address,” he insisted. This, too, he had learned in law school.

It was May 2, 1967, and the Black Panthers’ invasion of the California statehouse launched the modern gun-rights movement.

Governor Ronald Reagan, who was coincidentally present on the capitol lawn when the protesters arrived, later commented that he saw "no reason why on the street today a citizen should be carrying loaded weapons" and that guns were a "ridiculous way to solve problems that have to be solved among people of good will." In a later press conference, Reagan added that the Mulford Act "would work no hardship on the honest citizen."

The Mulford Act was a 1967 California bill that prohibited public carrying of loaded firearms without a permit.[2] Named after Republican assemblyman Don Mulford, and signed into law by governor of California Ronald Reagan, the bill was crafted with the goal of disarming members of the Black Panther Party who were conducting armed patrols of Oakland neighborhoods, in what would later be termed copwatching.[3][4] They garnered national attention after Black Panthers members, bearing arms, marched upon the California State Capitol to protest the bill.
