… A look back at former NYPD detective Frank Serpico - Washington Times.

“I don’t believe in the term ‘crooked cop,’ there is no such thing,” he said. “You are either a cop or you’re a crook. They are crooks in police uniforms. Some of these guys are cowards and hide behind the police shield and they call honest cops like me oddballs. Police corruption does not occur in a vacuum. It needs to be fertile ground for criminal-minded seedlings to take root. The myth that the department corrupts these innocent, civic-minded individuals is bogus. You must have larceny in your heart to begin with.”
