Chris correct me if I'm wrong but the only thing you can be cited for at a dui check point is a dui at least I'm pretty sure that's how it is inOhio. So unless he suspected him of being drunk he should of been sent on his way. As far as the ID goes, you do not have to surrender your ID unless you have commited or suspected of comming a crime. Since this was a dui check point and since all they are allowed to check for is dui and since they never said the think he was ssuspected of being drunk he shouldn't of had to surrender his I'd either.
