Jamaican posses, often referred to simply as posses, are a loose coalition of Jamaican gangs, based predominantly in Kingston, Montego Bay, London, New York City and Toronto, first being involved in drugs and arms trafficking in the early 1980s.
[1] The JLP posses dominate the west and south of Kingston and other smaller towns, while the PNP posses are mainly found in the eastern and central side; there are a few that state they are not allied to either political party.
They are strongly populated in London and are specifically known to have occupied and operate in Brixton, Harlesden, Tottenham, Hackney and Peckham among other areas.
Jamaican Posse members are known for gun battles with the police and drive-by shootings in disputes with rival gangs over drug turf, as well as for ritualized murders of members who "rip off" profits on drugs.
