A former Alabama state trooper has pleaded guilty to killing a black protester at a civil rights march 45 years ago. Seventy-seven-year old James Bonard Fowler pleaded guilty to second-degree manslaughter two weeks before he was set to go on trial for the 1965 death of Jimmie Lee Jackson. Jackson’s slaying set off a protest march in nearby Selma that became known as “Bloody Sunday” when Alabama police attacked demonstrators crossing a bridge. The Rev. Martin Luther King, Jr. preached at Jackson’s funeral. Fowler has been sentenced to six months in prison.
