The Clock Ticks Down for Troy Davis

As his execution approached at 7pm tonight in Georgia, Troy Davis refused a special last meal while supporters planned vigils outside the prison and at US embassies in Europe. Despite appeals from former President Jimmy Carter, Pope Benedict XVI and former FBI director William Sessions, Davis appeared to have exhausted all his legal options. Witnesses have recanted their testimony, some jurors say they've changed their minds, but retired District Attorney Spencer Lawton of Chatham County says Troy Davis is guilty of killing a policeman in 1989. Brian Evans is a campaigner for Amnesty International USA's campaign to Abolish the Death Penalty.
