I think it should be banned because its barbaric and does not deter would be murderers. But I'd prefer a democratic process to ensure its removal.
Perhaps the USA should follow the UK and either have a referendum or a thorough debate on this controversial topic, which the UK had some decades ago following the hanging of a completely innocent man. The recent horrific incident involving a botched lethal injection execution should set people thinking about the death penalty and its purpose.
Each state with the death penalty still active ought to have it as a priority political issue because such things are at the heart of a civilised nation and reflect its moral stand. An eye for an eye should no longer be the case, this is outmoded thinking and belongs back in the middle ages.
The death penalty, according to all reports and statistics, doesn't lower murder rates so what argument is there for retaining it on deterrent grounds?
Death row is cruel and mentally torturous.
