Today, the San Francisco Veteran Police Officers Association (SFPOA) has filed a lawsuit, supported by the National Rifle Association, in federal court challenging San Francisco’s recent ban on the possession of magazines capable of holding more than ten rounds. The Second Amendment-based legal challenge is part of a campaign of nationwide litigation filed and supported by a variety of law enforcement officers and associations to confirm that the Second Amendment protects these common standard-capacity magazines for self-defense and sport shooting.
