The death penalty

It is absurd and barbaric that democratic countries like the USA continue to use the death penalty. I am well aware of how horrible it is to know and tolerate someone who has murdered an Innocent person and I totally agree that they must be punished. But it all goes horribly wrong when the justice system gets it all wrong and the state ends up murdering someone who was Innocent and as long as there is even a 0.1% chance that someone could be Innocent then taking their life is completely and totally wrong and barbaric!
