Bottom line: you are not required, by Hiibel or by the ORC to supply any identifying information unless certain circumstances apply.
ORC 2921.29 says:
(A) No person who is in a public place shall refuse to disclose the personís name, address, or date of birth, when requested by a law enforcement officer who reasonably suspects either of the following:
(1) The person is committing, has committed, or is about to commit a criminal offense. (sounds like the requirements for a legal Terry stop, eh?)
(2) The person witnessed any of the following:
(a) An offense of violence that would constitute a felony under the laws of this state;
(b) A felony offense that causes or results in, or creates a substantial risk of, serious physical harm to another person or to property;
(c) Any attempt or conspiracy to commit, or complicity in committing, any offense identified in division (A)(2)(a) or (b) of this section;
(d) Any conduct reasonably indicating that any offense identified in division (A)(2)(a) or (b) of this section or any attempt, conspiracy, or complicity described in division (A)(2)(c) of this section has been, is being, or is about to be committed
cop} "May/Can I see some ID"?
me} "May/Can I hear some RAS"? then I shut up, if he persists in demanding ID without stating RAS my next statement will be "You have just opened the door to a Chapter 42 US Code 1983 Civil Rights Law Suit, am I free to go"?
"Am I free to leave? No? I have nothing further to say without my attorney present."
