That was a rather preachy fellow who should learn when to shut up, and a hostile and sadly misinformed cop. Interesting incident, though, thanks for the post.
EDIT: I checked into Ohio open carry law and found this:
If there's no other laws addressing open carry of a handgun, seems pretty clear that this clause protects the right to open carry. I know there are people here who don't like the open carry guys like this one, who carry to make a point, but I'd rather have them carrying than having them told they aren't allowed, with no law saying so.Sec. 9.68. (A) The individual right to keep and bear arms, being a fundamental individual right that predates the United States Constitution and Ohio Constitution, and being a constitutionally protected right in every part of Ohio, the general assembly finds the need to provide uniform laws throughout the state regulating the ownership, possession, purchase, other acquisition, transport, storage, carrying, sale, or other transfer of firearms, their components, and their ammunition. Except as specifically provided by the United States Constitution, Ohio Constitution, state law, or federal law, a person, without further license, permission, restriction, delay, or process, may own, possess, purchase, sell, transfer, transport, store, or keep any firearm, part of a firearm, its components, and its ammunition.
EDIT2: I listened through the end of the show, and was interested to hear that the hostile officer was reprimanded and an apology offered to Brian. Brian also stated that he would probably say the minimum possible instead of being preachy next time, saying he was flustered after being told to get on his knees and put his hands on his head.
