Would the sign still be legal in your eyes if it said concealed firearms?
No, it would not. At least not in the sense I intended. Sure they may place that sign there if they choose, but changing the sign from "no firearms" to "no concealed firearms" would prevent them from enforcing NRS 202.3673 at all as they have then not properly posted every entrance with the proper signage as required by that same NRS. It is really a matter of poor wording in the NRS, but it is what it is, and because of that the sign must be as is in order to enforce. Changing the sign IS simple enough, but changing the NRS so that the "no concealed firearms" sign is acceptable would be required first, which I don't think they'll even attempt to do.
It's just much simpler for them to "retrain" the officers that OC is not covered, leave the sign as is so that they can enforce 202.3673, and take the "bonus" that some OCers may be duped that "no firearms" really means no firearms.
The Government is not serving us if they are being misleading. And since it appears intentional, as you admit I will bet there is a statute. (Free beer if someone finds it)
If by chance they are not breaking a written law, they are shirking their duty to "protect our rights" as I pointed out in the video.
The deters part is an infringment on my 2-A which I find fully unacceptable, if LEO wants to serve me in this fashion, LEO is in the wrong business. We do not pay them to "fool" us.
I totally agree with the sentiment of this, but the truth is, that LEO have been allowed and, actually encouraged to "fool" citizens for decades. It actually IS a part of their job and has been upheld by many a court case. They do so in the name of "protection" and "law enforcement". Take a look at any of the other threads here that talk about not talking to officers, at all, due to the manipulative questioning and such. It is essentially the same situation, except this time they are using a printed sign instead of spoken words. LEO has every legality to lie to you, you are just not allowed to lie back.
Suggesting that you can be arrested IS too far and IS illegal as you suggested in your video. That IS coercion and will surely be "trained" away. But, telling you that firearms are not allowed is simply just a lie. In fact, telling you that it's illegal is simply just a lie. It is not coercion until you are threatened with force or detainment (or some other penalty) in an attempt to stop you doing an act that is in fact legal. Simply stating that it is illegal without suggesting that there is any consequence for violating the falsehood does not constitute coercion.
I applaud your efforts and fully support them and you. I'm glad you see my comments in the good hearted fashion they are intended. I hope in some way the alternate perspective will help your fight and perhaps give a chance to pre-think their possible moves so that you can be ready should any of my suggested possibilities come to pass.
Thank you for your work and efforts. You're doing great!
