As a result of that meeting the idea of forming an Association that could further assist retired Detectives with retirement benefits and to do charitable work came to fruition. This group decided to meet again that following month to continue your efforts and also to begin a life long bond that law enforcement officers share especially Detectives. The RDNY Incorporated later that same year and became officially known as The Retired Detectives of the City of New York.
