They may detain you to determine if you are licensed to carry a handgun. If he'd been carrying a rifle or shotgun, it would be different.
Indiana's handgun carry infringement is crap compared to most states.
Don't forget IMPD has new policy that they are not to bother people OC unless they are actually doing something wrong
