The Rastafarians have been a social problem for Jamaica ever since 1933, when one of their earliest leaders, Howell, sold 5000 postcards of the Emperor Haille Selassie at a shilling each making them out to be passports to Ethiopia. They gained greater publicity in 1941 when the police raided Howell's community at Pinnacle and arrested seventy of his followers on charges of growing ganja (marijuana) and of violence. In the 1950's many more were arrested, and - Rastas assert - flogged and forcibly shaved by the police; some were imprisoned on charges of rioting, and there were two separate cases charging that children were sacrificed by fire in Trenchtown, a slum area of the capital.
