So, why do you continue to count all of those municipal ordinances superseded by state statute in your count of gun laws?<quoted text>
Per O.R.C. 9.68, all firearm laws in Ohio, except those restricting the discharge of firearms and certain zoning regulations, supersede any local ordinances. This restriction on municipalities was upheld by the Ohio Supreme Court in the cases of OFCC vs. Clyde (2008) and City of Cleveland vs. State of Ohio (2010).
Note how recent a phenomena that is.
As an aside, while that specific statute may be recent, the inability of a municipal ordinance to supersede a state statute is longstanding.
