If you follow gun law and politics you may know that a federal judge ruled not to long ago that California's concealed carry laws violated the Constitution. In short, California has what is called a "may issue" law. If you wish to carry a firearm you apply to the local sheriff and he decides whether he wants to give you a permit. Generally under a "may issue" system it is up to you to convince the sheriff that you need to carry. It is not enough that you want to. Since the system depends on the whim of the sheriff, the reality is that most applications are denied outright.
An alternative system such as that in effect here in Washington is called a "shall issue" system. Basically the state acknowledges that the people have the right to self defense and anyone who wants a permit, if they can pass a background check, gets one.
The government of California, predictably, appealed the ruling and lost the first round.
