California has some of the toughest gun laws in the nation, including a ban on the type of high-capacity ammunition magazines used in the nation’s three most recent public shootings, which claimed nearly three dozen lives. How long those types of laws will stand is a growing concern among gun control advocates in California and elsewhere. (AP Photo/Rich Pedroncelli, File)
