Call up your local PD and ask them what thier policy is, its very hard to find that type of stuff on line.
in CA, you are required to hand over your permit and your gun if asked by a LEO. you don't have to tell them you have a CCW, but you do have to hand it over if they ask.
Depending on rahter it was yolo or placer county, the fact that he had a federal duty gun may have been the only reason he got the CCW.
We don't know if his ccw was surrendered, suspended or revoked.
I'm guessing its the 1st or 2nd.
