Just carry a gun like we do here in Texas. Oh wait......it’s California. Never mind.
California is odd...just stay with me here...in that depending on which county you live in determines if you can get a concealed carry permit. Fresno county has granted over 7500 out of a population of 950,000, Shasta county has 5900 out of a population of 180,000. But L.A. county with a population of over 10,000,000 has 560 legal concealed carriers. And then there’s the City & County of San Francisco which has granted 2 for a population of over 850,000.
Obviously the safest places in CA are SF & LA counties.
