I think in most cases it all depends on the deputy/LEO. In gun-friendly areas, there are still the Barney Fife's who think they are the only ones who should able to carry - PERIOD. And vice-versa. In Ohio, you can legally open carry or obtain a CHL to conceal carry. But I think there is a stipulation that if you are CCWing, it has to been concealed and, some LEO might make an issue based on that.
I would say MOST LEO's that I have encountered would have done the same as the OP experienced. The LEO's I know personally are all pro-2nd admendment and support/encourage citizens obtaining a CHL.
