How authorities broke up an extortion ring in the 1960s that targeted gay men:

“Impersonating corrupt vice-squad detectives, members of this ring, known in police parlance as bulls, had used young, often underage men known as chickens to successfully blackmail closeted pillars of the establishment, among them a navy admiral, two generals, a U.S. congressman, a prominent surgeon, an Ivy League professor, a prep school headmaster, and several well-known actors, singers, and television personalities. The ring had operated for almost a decade, had victimized thousands, and had taken in at least $2 million. When he announced in 1966 that the ring had been broken up, Manhattan DA Frank Hogan said the victims had all been shaken down ‘on the threat that their homosexual proclivities would be exposed unless they paid for silence.’

“Though now almost forgotten, the case of ‘the Chickens and the Bulls’ as the NYPD called it (or ‘Operation Homex,’ to the FBI), still stands as the most far-flung, most organized, and most brazen example of homosexual extortion in the nation’s history. And while the Stonewall riot in June 1969 is considered by many to be the pivotal moment in gay civil rights, this case represents an important crux too, marking the first time that the law enforcement establishment actually worked on behalf of victimized gay men, instead of locking them up or shrugging.”
