Geneva, May 12 (RHC)-- The United States has faced questions over police violence at the United Nations Human Rights Council in Geneva. The questioning came as part of a universal periodic review, which takes place every four years.

Member states grilled the United States over its failures to close Guantanamo prison, prosecute perpetrators of CIA torture and address violence against Native American women. But the review focused on racism and police brutality, an area where U.S. Justice Department official James Cadogan acknowledged the United States must improve.

Attending the review of the U.S. human rights record in Geneva was the brother of Rekia Boyd, a 22-year-old African-American woman fatally shot in the back of the head by an off-duty Chicago police officer in 2012. Last month, Dante Servin was found not guilty after killing Boyd and shooting and injuring her friend. Servin claimed he thought the friend had a gun, although none was found. Martinez Sutton called for justice in his sister’s death.
