The Black Mafia, also known as the Muslim Mafia, Muslim Mob, Philadelphia Black Mafia, or PBM is a Philadelphia-based African-American organized crime syndicate.
 The organization began as a small criminal collective, known for holding up neighborhood craps games and dealing in the illegal drug business, but at its height of operation until about 1975, it managed to consolidate power and control a large portion of criminal activity in various African-American neighborhoods throughout Philadelphia, the Delaware Valley, and South Jersey, including Atlantic City.
 In addition to drug trafficking, burglary, and armed robbery, the Black Mafia was also engaged in traditional organized crime activities such as extortion, racketeering, prostitution, loansharking, number running and other illegal gambling rackets.
The numbers game, also known as the numbers racket, the policy racket, the Italian lottery, the policy game, or the daily number is a form of illegal gambling or illegal lottery played mostly in poor and working class neighborhoods in the United States, wherein a bettor attempts to pick three digits to match those that will be randomly drawn the following day.
 In recent years, the "number" would be the last three digits of "the handle", the amount race track bettors placed on race day at a major racetrack, published in racing journals and major newspapers in New York.
 A gambler places a bet with a bookie at a tavern, bar, barber shop, social club, or any other semi-private place that acts as an illegal betting parlor.
Operation "Bishop" is the codename for a longterm effort by state and federal police forces to end illegal gambling and associated money laundering schemes in the border city of Brownsville, Texas.
 Since its beginning in April 2013, Operation "Bishop" has focused on "eight-liner" establishments, where customers play inexpensive slot machines, known as ""maquinitas"", and so far have made over 60 arrests, seized over $1,000,000 and dozens of slot machines, in more than 70 police raids.

 The bill was passed on 29 July, 2002 to take effect with its publication in the Government Gazette, pursuant to the enabling article.
