Brent was chosen because it had more shootings than any other area of London. Two gangs in Harlesden, the Lock City Crew and the Much Love Crew, were linked to violence for control of the crack trade, although other criminals were also fighting for a stake. Some gunmen were fugitives from Jamaica, but most were born in Britain. Last year the body of Affar Tikur, 21, was found in a reservoir. Tikur, who had ignored his mother's pleas that he abandon the crack trade, was killed by six bullets to the back of the head.
