How does having a cased rifle locked in your car trunk do anything to make you safer in absence of a CCW?
Ok, so Mr. RM23 and his lovely wife and kids are coming out of Applebee's discussing the lovely faux wall decorations
Suddenly, John W. Crackhead is right at the outside door, starts begging you for money politely, you keep telling him no and he won't listen, finally he starts more and more angry and in your face and eventually pulls out a knife on you and starts demanding your wallet.
What do you do now? Shove him away, run 50 feet to the car, pull out the car keys, open the trunk, snap the 2-4 latches on the case open, pull the gun out of the trunk, (i'm assuming it's loaded, otherwise, insert magazine, cycle action) aim at him and gun him down from across the parking lot?
How can you justify that as self defense in the court of common sense???
That's ridiculous. The beretta in the trunk is not keeping you any safer. It sounds to me like you own a magical security totem, not a firearm. And you did something very irresponsible with it by leaving it out. A good cop did you a big favor and instead you complain he wasn't sure what a barrel shroud is. Despite the fact that he was polite, asked a superior who did know, and inconvenienced you as little as possible and potentially prevented a very serious crime.
My advice to you, leave the security totem inside.
