I think you missed my point which was that we ultimately need more clarity in our OC and concealed laws because they are open to interpretation. But if you want to challenge authority by going half concealed then that is your option, but a cop may not (yet) think it is your right.
There are no OC laws. Half-concealing is only a grey area if you do not possess a CPL. That is because it is not codified in law as in other states, such as Virginia.
