If there is a duty to inform law in effect, and you don't inform the cop, then when/if he/she sees your gun they will draw on you, and you might even get shot if you don't exactly comply with instructions next.
Best thing is always to obey the law -- stupid law or not.
Stupid laws come from stupid legislators who were elected by stupid people.
Calif, NYS, Mass., NJ, and certain cities like Chicago and DC are loaded with stupid people and stupid laws like this.
You sir, just won the internet.
I spent over 25 years as an officer with a city agency here in AZ. My career spanned the time when Arizona went from permitless open carry, to concealed carry with a permit, to finally Constitutional Carry, which I personally applaud.
Do I think that you should be legally
compelled to inform an officer? Meh, probably not. Mainly because I come from Arizona, and I just assumed everyone who wasn't driving a VW Beetle or Prius with rainbow stickers or Obama or Hillary for prez-o-dent bumper stickers had a gun in the car. Did I get worked up about it? No...why get worked up? In most cases, I already knew if you were a chud or a demonstrably solid citizen before I approached the car...computer technology...not ESP.
If, when I asked you if you were armed and you told me yes, and where it was my answer was "Thanks for letting me know. Just keep your hands away from it, and we won't have to make noise and do paperwork, okay?"....and I
always asked because I didn't want to be the poor bastard who filled you full of 45 hollowpoints because you had a pistol in your glove compartment,
sitting on top of your registration and insurance card, and didn't tell me about it and it looked a LOT like you were going for the gun instead of your documents even after I told you to STOP!.
Yeah, almost happened one night and the goober driving the car almost got
dead of stupid, but thank GOD he stopped before I addressed him with the muzzle of my Glock. His gun was sitting on top of his documents and he put his hand on the grip frame to move the gun to get his docs. Situationally....not a good idea. Thank God for BOTH of us that it worked out.
On the other hand...
If I pulled someone over and they said (as I advocate)..."I just want to let you know that I have my permit, and I am carrying, it's on my _______", my answer was "Cool, thanks for letting me know.
I don't need to see it, so leave it where it is. The reason why I pulled you over is _______________, may I have your license, registration, and proof of insurance?".
Go back to MDT, if they are a solid citizen with a lack of PD contact (bad behavior, or civil traffic in a while), then I went back and said "Okay, Christmas is early, I am just giving you a warning. Slow it down, get it fixed (whatever was appropriate to the moment), and be good for the next six months because the next officer will have to issue you a citation. Have a nice evening".
Traffic was not my bailiwick, I worked a different division, but once in a while someone did something to get my attention and make me say "They really want to talk to me"...like speeding in a school zone which is a BIG no-no here in AZ, but mainly it was a case of suspected DUI that caught my attention. If the driver was clearly not impaired, then I damned sure wasn't going to hang paper on a decent dude "just because I could". I cut breaks when I was able, it made my job easier not to be a jerk (like my brother who works motors in another city and gets a stiffy when he can write a ticket), and usually getting a warning was more than enough to modify behavior. Win win.
NOTE: All of this was predicated on the fact that the driver was NOT being a d-bag.
On the other hand...I personally LIKED and appreciated it when someone informed me. It usually meant that they had nothing else to hide, and were trying to be helpful. I rarely, and I mean RARELY ever took possession of someone's gun, but it was always determined by the totality of the circumstances. There had to be a reason for me to do it because any extra handling of a loaded gun when it is not
immediately necessary is a recipe for disaster.
Sadly, and this is where we find ourselves...officers are no longer being trained as "peace officers", but rather "law enforcement" officers and they are losing discretion on the street. Some departments have instituted "must cite" policies and the men and women on the street are in a limbo between trying to do the job the right way with common sense, and having to walk the tightrope of policy made by lardbottoms who haven't been off a desk in a decade.
Do I advocate informing an officer? Yes...for the reasons above, but it's preference. If more people acted like adults....ahhh...lamentations.
