Well, I checked Wiki for the Crips:
http://en.wikipedia.org/wiki/Crips
And the Black Panthers are mentioned twice:
Gang activity in South Central Los Angeles has its roots in a variety of factors dating back to the 1950s and 60s including: post-World War II economic decline leading to joblessness and poverty, racial segregation leading to the formation of black "street clubs"
by young African-American men who were excluded from organizations such as the Boy Scouts, and the waning of black nationalist organizations
such as the Black Panther Party and the Black Power Movement
People in the neighborhood then began calling them cripples, or "Crips" for short.[17] The name had no political, organizational, cryptic, or acronymic meaning.
Williams, in his memoir, further discounted claims that the group was a spin-off of the Black Panther Party or formed for a community agenda, the name "depicted a fighting alliance against street gangs?nothing more, nothing less", Williams wrote
Wiki doesn't mention the Black Panther party on its Bloods page at all , so this would seem to contradict that the Crips were formed from the Black Panther Party.
