Some of you need to read the comments in his blog, where people are stating the Ohio Revised Code.
One states that unless he is accused of shoplifting, they cannot search him or his property without consent. They didn't accuse him, and he didn't give consent. He was within his right to deny them anything.
The second states that in Ohio, he is only required by law (unless operating a motor vehicle, which he wasn't), to only provide his name, DOB, and address to law enforcement. He states they only asked him for his name, which he gave them and had the officer asked him for additional information, he would have provided it. He was not required to provide his driver's license by law.
So he is correct in defending his rights, whether you agree with his approach or not. Is he being a dick about it and making it more difficult than it needs to be? Yes. Is he also fighting the system for what he believes in? Yes.
