A study in the British medical journal The Lancet suggests that, despite the presence of a Canadian-led United Nations police force and UN peacekeepers, 8,000 people have been killed and 35,000 women and girls raped in Port-au-Prince alone since the ouster of then-president Jean-Bertrand Aristide in 2004. In the study, published online in The Lancet yesterday, two (unidentified) researchers at Wayne State University\'s School of Social Work interviewed 5,720 people in 1,260 Haitian households in December 2005, asking questions about their lives in the 22 months since Aristide\'s fall.
