On 20 April 2017 the California Assembly Passed AB7 which closes a “loophole” banning open carry of non-handgun related firearms.
The bill covers non-handgun firearms specifically and is designed to close a “loophole” regarding unincorporated areas. California banned “Open Carry” essentially because a YouTube Video made people realize that open carry was legal and police didn’t know how to react to it.
Like all nanny-state measures the reaction to learning that Californian’s had a freedom they didn’t like the legislature ran to ban something. Now they’re simply back to making sure it’s MOAR BANNED.
