FILE - In this Friday, Jan. 28, 2011 file photo, a woman grieves at the coffin of gay activist David Kato in Mukono, Uganda. As a prominent Ugandan gay rights activist, his picture was published by an anti-gay newspaper next to the words "Hang Them." He was killed on Wednesday, Jan. 26, 2011. Police said Thursday his sexual orientation had nothing to do with the killing and that one "robber" had been arrested. Uganda has been under scrutiny by international gay-rights groups since 2009, when a lawmaker proposed a bill that would mandate the death penalty for some gay acts. (AP Photo/Michele Sibiloni)
