Lethal injection

Only a few days ago, the United States Supreme Court gave leave to appeal with respect to the constitutionality of lethal injection as a method of execution. The Court has only rarely dealt with method of execution and the last ruling on the subject dates back, I think, to the 19th century. This issue has the potential to knock out the death penalty in the United States entirely. Amnesty International has just issued a very useful document on the subject of lethal injection: http://web.amnesty.org/library/Index/ENGACT500072007?open&of=ENG-392
