STEPHEN SHAMES: In response to the Panthers' police patrols, Governor Ronald Reagan of California signed the Mulford Act in 1967.
BOBBY SEALE: They did it because of the Black Panther Party. They made the law say, "No one can carry a loaded weapon within city limits." And within 150 feet of public property inside city limits. Public property included all roadways, which means that you would have to be 150 feet from a public sidewalk before you could load your weapon. I'm not going to go out and patrol police without a loaded weapon. So we stopped patrolling police.
STEPHEN SHAMES: The National Rifle Association did not utter a peep of Second Amendment protest. Can you imagine what they would say if President Obama proposed a national Mulford Act today?
