NYC Police Union Reducing Number of “Get Out of Jail Free” Courtesy Cards

In the movies I’ve seen people who try to get out of a traffic ticket by telling the police officer they made a donation to the policeman’s ball, but those were comedies. I had no idea that not only does this exist there are official cards. In fact, the police in New York are liv … | Continue reading
