All I can find is reference to the following for bpsn.
The Black P Stones are a large and infamous African American street gang founded in Chicago, Illinois but later expanded to Los Angeles, California in the late 1960’s. It was the year 1969 when the Black P. Stones first emerged in California operating out of the West Adams area of Los Angeles near Crenshaw Blvd. OG T. Rogers, a member of the Chicago Black Stone Rangers, moved to Los Angeles and started a local chapter. The Black Stone Nation was originally formed in Chicago , Illinois and is one of the few Los Angeles gangs that has a history that goes back to another city. During the early to mid 1960s, The Blackstone Rangers formed on the South side of Chicago. They were later identified as the “Black P. Stone Nation”, then years later as the El-Rukns. Still a teenager, OG T. Rodgers was asked by the “Black P Stone Nation” to start a California division. He began in Jefferson Park, and he ended up building one of the most notorious Blood sets in Los Angeles, creating a money making empire, and making the Jungles in LA a haven for Bloods. There are an estimated 700 members of the Black P Stones, 400 of whom live in Baldwin Village.
