I agree that we shouldn't accept a lower standard of proof. However, life in prison isn't absolute in the same the death penalty is. There's always a small chance of the evidence changing and the justice system being able to rectify the mistake. There have been several convictions overturned because witnesses changed their story or were later found to be not credible, sometimes decades later. Once the death penalty is carried out, there's no going back.
