Author and former NYPD Officer Joe Sanchez

(born: January 16, 1947), is a highly decorated former New York City police officer and author whose books give an insight as to the corruption within the department. Upon exposing the illegal acts committed by some high ranking officers, he was betrayed by the Internal Affairs Division and arrested on the false allegations of committing various crimes in a case which was highly publized by the news media. He was found guilty for the assault charge, a conviction which was overturned. His case exposed the existence of a code of silence among police officers known as the "Blue Wall of Silence".
