I've heard airports like LAX have been arresting people and confiscating handguns. Are those incidents of people who were visibly (and in my mind foolishly) carrying in the passenger compartment, or are the police preemptively searching cars that enter airport property and confiscating arms that are being lawfully transported in locked containers in the trunk of the car?
There are preemptive check points where vehicles are searched by officers and dogs at the Sepulveda ramp. Not sure if this is what the OP is referring to where handguns or guns in general are seized.
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!
