 During this period, the Haitian National Intelligence Service (SIN), which had been set up and financed in the 80s by the Central Intelligence Agency as part of the war on drugs, participated in drug trafficking and political violence.In December 1990, Jean-Bertrand Aristide, a liberation theology Roman Catholic (Salesian) priest, won 67% of the vote in elections that international observers deemed largely free and fair.Aristide's radical populist policies and the violence of his bands of supporters alarmed many of the country's elite, and, in September 1991, he was overthrown in the 1991 Haitian coup d'état, which brought General Raoul Cédras to power.
