Friends of Jose Luis Salas, 24, one of the 17 men killed in a rehab center, carry his coffin out of a church after a funeral service in the border city of Ciudad Juarez September 5, 2009. About a dozen hooded men burst into a clinic in the violence-plagued industrial city of Ciudad Juarez, across from El Paso, Texas, on September 2, lined up patients and killed 17 of them. Drug gangs have targeted rehab centers in the past, accusing them of protecting dealers from rival groups. REUTERS/Tomas Bravo (MEXICO CONFLICT CRIME LAW POLITICS)
