During the 1980s and 1990s, Jamaican posses captured the imagination of the press corps, film makers, and numerous of criminal justice scholars in the United States. However, except for a few historical references, their virtual disappearance from the contemporary criminal justice literature leaves many unanswered questions. In updating the literature, this paper examines the main factors contributing to the decline of Jamaican posses in the United States and explains how their criminal activities were displaced to Jamaica through aggressive U.S. anti drug and anti-gang operations and immigration policies.
