I don't know of any legal concept that allows a person to be arrested for the sole reason of not providing identification. They can only ask you for your driver's license during a traffic stop because you're driving a car, which requires being licensed; if you're standing at the side of a road minding your own business, they have no right to demand anything from you. You should be able to just stand there and not say a word. The old guy was acting like an ass, but he didn't commit a crime, and therefore I don't think he should have been arrested for anything. If this held up in court it would set a legal precedent for requiring people to have identification on their persons at all times.
