Yesterday the US Supreme Court abolished the death penalty for convicted killers under 18 years of age at the time they committed their crimes.
I think that one of the most powerful arguments against the death penalty is that there are always going to be innocent people who are wrongly executed, and is that a price that a civilized society can afford to pay? Also, does the threat of execution actually act as a deterrent as is often claimed by proponents of the death penalty? The evidence points to the fact that it does not. Certainly, in the UK, where there is no death penalty, there is less violence in society than in the US States that have the death penalty. Additionally, the people sentenced to death in the US are often black, due to racial bias in sentencing ... can black people afford to support the death penalty while this bias continues?
