Black Brothers, Inc. : The Violent Rise and Fall of Philadelphia's Black Mafia
Sean Patrick Griffin  More Info

Sean Patrick Griffin, Ph.D. is a former Philadelphia Police Department police officer who is now associate professor in the Administration of Justice at Penn State Abington. He has authored numerous articles on organized and white-collar crime and been an invited panelist on national crime forums.  He is the author of Black Brothers, Inc.: The Violent Rise and Fall of the Philadelphia Black Mafia.


According to Sean Patrick Griffin’s publisher, “In June 2005, a prominent and politically influential Muslim cleric, Imam Shamsud-din Ali, became the latest person convicted in a massive federal corruption probe in Philadelphia. As the revelations emanating from the probe continue, a critically acclaimed author and leading authority on organized crime exposes for the very first time the disturbing contemporary and historical ties between Ali, the city's notorious Black Mafia, and the sweeping federal probe.


The Black Mafia was one of the bloodiest crime syndicates in modern US history. From its roots in Philadelphia's ghettos in the 1960's, it grew from a rabble of street toughs to a disciplined, ruthless organization based on fear and intimidation with links across the Eastern Seaboard. Known in its "legitimate" guise as Black Brothers, Inc., it held regular meetings, appointed investigators, treasurers and enforcers, and controlled drug dealing, loan-sharking, numbers rackets, armed robbery and extortion.


Its ferocious crews of gunmen grew around burly founder Sam Christian, the most feared man on Philly's streets. They developed close ties with the influential Nation of Islam and soon were executing rivals, extorting bookies connected to the city's powerful Cosa Nostra crew, and cowing local gangs. The Black Mafia was responsible for over forty killings, the most chilling being the 1973 massacre of two adults and five children in Washington, D.C. Despite the arrests that followed, they continued their rampage, exploiting their ties to prominent lawyers and civil rights leaders. A heavy round of convictions and sentences in the 1980's shattered their strength — only for the crack-dealing Junior BlackMafia to emerge in their wake.


Researched with scores of interviews and unique access to informant logs, witness statements, wiretaps and secret FBI files, Black Brothers, Inc. is the most detailed account ever of an African-American organized crime mob, and a landmark investigation into the modern urban underworld.”
