CALIFORNIA
California does NOT honor ANY other states' concealed carry permits.
And the laws here are arcane and if you are unfamiliar with how to comply with them and you bring in a handgun from another state the odds are you will fall afoul of them.
The odds are also that you will not be caught but if you do they will take a pound of flesh. Yes, it violates the Constitution and yes it is intolerable and yes I work to get the law changed. But, as the old proverb says "The nail that stands up gets hammered down." And I'm not risking the few remaining gun rights I have just try and to prove a point.
Bureaucrats in California honor permits for current and retired law enforcement. "Rules for thee but not for me."
By honoring those but not others, California bureaucrats are violating the equal protection under the 14th Amendment.
