That was part of the COINTELPRO plan/policy. That isn't conspiracy theory either it's well documented now.
Also we can speak about the FBI collusion in the assassination of the very eloquent Fred Hampton in 1960 in Chicago.
The Black Panther Party was a broad church with many good and many bad people associated with it.
To blanket condemn them or blame them for the problems in black communities of the 80s and 90s (as was done by Kokolicious is very lazy and ignorant thinking which is why I felt the need to counter it). There is amble research out there to draw on that would refute that almost entirely. There have always been severe problems in 'ghetto' communities, and they are to do with lack of opportunity which come from poverty and racism, poor education, bad housing, etc. etc. You find that in the UK also, where I am from, which never had the Black Panther Party (certainly not in the form of the US version anyway).
