U.S. District Judge Cormac Carney has granted a preliminary injunction blocking a California law that would have prohibited people from carrying concealed firearms in most public places, ruling that it violated the Second Amendment of the U.S. Constitution. The injunction was granted in response to a lawsuit filed by the California Rifle & Pistol Association, and the law will remain blocked until the case is resolved. This outcome could have major implications for gun control laws in California and across the country.
