As the way the illegal/unconstitutional law is written...
Yes, even if a mere passenger, you will have to declare...which is ridiculous.
If mere casual encounter, no real need to declare... for instance I was putting up a garage sale sign, I didn't declare because I was not being detained or anything...it was a "courtesy" thing as I was already pulled over and he was just seeing what was going on.
As for "printing", that is still concealed. Some part of the actual weapon must be displayed, nothing over it to be considered open carry. So basically, if you have a IWB holster and you have no shirt on (thus exposing the grip) you will actually be open carrying.
I have never had anyone ask if I was armed, but I think I would say something smart-ass like "That's kind of personal, you haven't even bought me a drink yet."
Of course as far as I am concerned, it's none of anyone's business, especially not government...and don't declare for much of anything.
The officers safety is not any more important than anyone else's...also, who is going to protect the individual from the cop? They are merely other people, another person with a firearm...nothing more.
It is a violation of the 2nd and 4th amendment to have such a law requiring disclosure of any kind...not to mention no one has any business disarming someone unless they are actually going to arrest the person....that would be a seizure, even if it is only temporary.
But frankly, we need more open carry...the mere sight/idea of someone being armed should be nothing out of the norm in day to day life. It should bring no alarm. People need to start asking themselves "what is the person doing?" as in, are they waving it around or is it holstered...are they shouting/threatening or calm/collected...etc
