I've heard from LEOs and others that someone OCing can potentially be charged under the "inducing panic" statute. I thought it would be worthwhile to familiarize ourselves with the actual text, so here's the relevant section of the ORC (sorry if the cut and paste is inelegant):
§ 2917.31. Inducing panic.
(A) No person shall cause the evacuation of any public place, or otherwise cause serious public inconvenience or alarm, by doing any of the following:
(1) Initiating or circulating a report or warning of an alleged or impending fire, explosion, crime, or other catastrophe, knowing that such report or warning is false;
(2) Threatening to commit any offense of violence;
(3) Committing any offense, with reckless disregard of the likelihood that its commission will cause serious public inconvenience or alarm. -----
The statutegoes on at length with various definitions and exemptions for emergency drills and such, but it seems obvious to me that this law doesn't apply to OC, absent some overt threat being made.
Congrats on handling the matter without escalation or SWAT involvement or whatever the person calling it in expected.
