You can bet the farm that if an OCer was arrested in LA it'd be on the news.
I have been through LAX many times. I have searched for flights for a trip to meet-up with SBOC at one of their events; and my intent was to legally transport one of my wheelguns to the meetup (SBOC event, flight schedule, and my work schedule never seem to mesh).
I have never been searched by an LA Deputy Sherrif or LAPD. Their presence at the airport has been minimal.
I have never parked a car at LAX though. I have ingressed and egressed through the front door.
My guns have traveled by commercial airlines many times, and I they will continue to do so. I feel better about transporting my guns than giving up my 4A protections to TSA gate-rapists.
PS: I love it when TSA at small airports check my gun for GSR. I always remark: "You know, I was hunting and did bag some game with this gun!" Of course they find GSR--who-da-thunk!
