The court case in Ohio involves a homeowner that killed an intruder with an illegally purchased and unregistered gun. A character says it was purchased from an unlicensed gun dealer. Ohio has no such law. A person that is not a firearm dealer is in fact a private person selling a gun, and there exists no ban (yet) on such a transaction between two adult residents of Ohio. Additionally, Ohio has no gun registration, so no gun there is registered. In light of the above, there would never be a criminal charge against a homeowner in the described circumstances, so the jury deliberation would be non-existent.
When talking about the situation in Ohio, a character says Ohio is a concealed carry law state with people that like guns. While the state does issue permits, it is generally legal in Ohio to openly carry a handgun or long gun without a permit.
