Like Troy Davis last year, the Reggie Clemons case raises profoundly troubling concerns about the administration of capital justice in the US (Report, 22 August). Amnesty opposes the death penalty in all circumstances, but even the punishment's supporters must agree that it is unconscionable if there's the slightest doubt over guilt. Here there is ample. There was no physical evidence linking Clemons to the crime and there are serious allegations of police coercion (including severe beatings), prosecutorial misconduct and of a "stacked" jury at his trial. In a case where three African American men were tried for the murder of two young white women, there are also concerns over racial bias. Yet, as so often in these cases, the outcome of a substandard original trial may still kill a man. Clemons' execution is far from inevitable.
