It is not so much a problem as it is a nusiance. Technically, no one can observe you and detect the presence of a weapon. technically, they can report you. technically, there are legal implications which can be brought. Technically, a police person can bring charges.
I have never heard of this happening and I take great care to avoid any complications. I have, on occasion, felt as though I printed and it was, at least to me, disturbing.
I just don't need the frustration of zero tolerance if I run upon someone bent on creating a situation or LEO who wants too act like Wyatt Earp.
I have carried illegaly for many years without any problems and legally for the last 10 years with no problem, however; I am always very cautious and would prefer to not have too be.
That is, again, not to say I would wear open but would prefer to just to be able to wear naturally or act naturally.
