Sounds like the Government there fears Armed Insurrection. I think a remember a Power in 1775 that had the same concern for the same reasons as today. Even "Peaceful Protest" is feared?
Huh, lets see if Cali treats their public property (Entire Cities) as their private property then they can also regulate your speech, your clothing (If they find it offensive.) They can force you to leave. You have no right to be on anothers private property unless you do as they say. And it seems Cali is now OWNED by the Government there.
Remember, The Dear Leader said today, "I expect Responsible Gun Owners To Agree With Me."
Will we loose our trigger finger if we do not?
