Jungle justice

Jungle justice or mob justice is a form of public extrajudicial killings in Nigeria and Cameroon, where an alleged criminal is humiliated, beaten or summarily executed by a crowd or vigilantes. Treatments can vary from a "muddy treatment", where the perceived perpetrator is made to roll in mud for hours to severe beatings followed by necklacing. This form of street justice occurs where a dysfunctional and corrupt judiciary system and law enforcement have "lost all credibility. European principles of justice have likewise become discredited."
Notable examples include the Bakassi Boys and the Aluu four lynching.
