The PATH train between NJ and NYC also prohibits food and drink on trains and platforms. I personally love the law as it creates much cleaner trains. That being said, I've never seen the law enforced, not to say it isn't. In this case it appears the man didn't want to give his name or ID for the ticket, thus leaving the officer with his only option, arresting him. Whether it was racially biased, who knows from this one instance.
