Jack Ruby, originally known as Jacob Rubenstein, operated strip joints and dance halls in Dallas and had minor connections to organized crime. He also had a relationship with a number of Dallas policemen, which amounted to various favors in exchange for leniency in their monitoring of his establishments. He features prominently in Kennedy-assassination theories, and many believe he killed Oswald to keep him from revealing a larger conspiracy.
