A Superior Court judge in Los Angeles on Monday rejected claims by some entertainment industry businesses that a strict gun control ordinance would make it impossible to shoot an action movie within city limits.Superior Court Judge Robert O’Brien refused to block implementation of the city gun law that prohibits the sale or transfer of magazine clips carrying more than 10 rounds, among other requirements. Companies providing filmmakers with guns claim it would hurt business. “This ordinance effectively makes it impossible to film an action movie in the city of Los Angeles,” said plaintiff’s lawyer Chuck Michael. “The anti-self defense politicians who drafted this ordinance are woefully ignorant of firearms technology and the highly regulated firearms business.” O’Brien declined to issue a temporary restraining order against the ordinance and scheduled a hearing Dec. 9 on the plaintiff’s request for a preliminary injunction. “This is an important victory,” City Councilman Mike Feuer said in a statement. “It shows that local governments can enact sensible firearms control measures that will stand up to judicial scrutiny. … This law will save lives.” The ordinance, which went into effect Saturday, requires trigger locks be sold with every gun, mandatory background checks for all gun dealers, a ban on so-called Saturday Night Special handguns, and a thumb print for anyone purchasing ammunition. A coalition of gun dealers and entertainment industry-related companies have argued that the ordinance would be useless in preventing criminals from getting bullets from unauthorized dealers or purchasing from gun stores in other cities. The National Rifle Assn. has also said that such a law would violate the spirit of a federal law that forbids the government from establishing lists of weapons owners.
