At the weekly Board of Realtors meeting we had a special guest Assamblyman Jeff Miller, I left my gun in my trunk. Next week we will have Congressman Ken Calvert. Is there a law in California that prohibits me from UOC around them? I open carry there all the time and want to make sure I am not breaking any law.
Be very very careful - you might already be breaking the law if you don't have a CCW in your pocket. I don't have enough information about how a Board of Realtors meeting is legally classified, nor do you mention where the meeting takes place.
I would recommend you research CA PC 171b through 171f
In particular:
171b. (a) Any person who brings or possesses within any state or
local public building or at any meeting required to be open to the
public pursuant to Chapter 9 (commencing with Section 54950) of Part
1 of Division 2 of Title 5 of, or Article 9 (commencing with Section
11120) of Chapter 1 of Part 1 of Division 3 of Title 2 of, the
Government Code, any of the following is guilty of a public offense
punishable by imprisonment in a county jail for not more than one
year, or in the state prison:
(1) Any firearm.
