Unfortunately, while the Ohio Supreme Court stated that open carry is a fundamental individual right, no local ordinances that prohibit it were being challenged. This means that the court did not strike down any laws which prohibit the fundamental right of openly carrying. Many local ordinances still prohibit openly carrying a firearm. While these ordinances are unconstitutional, nothing stops those local governments from arresting you for openly carrying. A constitutionality challenge would then have to be mounted by your defense attorney in the courtroom.
