Simple, the only statute on IDing is IC 34-28-5-3 and -3.5. That's it. That's the only reference in the code to a requirement to ID, and it doesn't say that photo ID is mandatory. It says that photo ID is optional, along with the option to instead give name, addr, and DoB, all three of which are present on the LTCH anyway. And either are only required if suspected of an infraction (traffic) or (city) ordnance violation. No such requirement to ID is valid for suspicion of a misdemeanor, felony, or consensual interactions.
If anyone has any case law on the matter, let Kut know.
Thanks for the information, this is great to know. It will come in handy.
