I don't know, soon as the permit comes in (around the 23rd) I'm going to have my IWB holster on, uncovered, and make a point for a cop to notice me, just to gauge reaction, because hey, that's the "partially concealed" portion of the law if I ever saw it defined..
I think you are possibly onto what the law was intended to regulate with "or in part" as opposed to regularly openly holstered firearms.
