I don't know where you got that it says for "personal protection" as well as other lawfull purposes not self defense!
Why is that? You don't need a ccw to carry in a private means of convenience. That is the "LAW"
Your understanding is very flawed and I might suggest removing the tin foil and coming back to mother earth.
I am going to guess you have never been to law school just a guess? A LEO only needs reasonable suspicion to search your vehicle. Trust me you will loose in court it don't take much to give them that and telling them to FO wont work. Last but not least they don't need a warrant to search your vehicle!
Never ask a cop about the law that is like asking a cashier at the gas station about a medical problem it's rather silly.
That is the best part of your whole post.
