Missouri executed Marcellus Williams despite there being evidence that he was innocent. The family of the murdered woman asked that his sentence be commuted to life in prison so there was no pressure from them for execution. The county prosecutor found issues with his case and wanted further investigation. Missouri still went ahead because Williams was found guilty by a jury of his peers.
As if a jury sentence can’t be wrong when we know that human institutions are wrong all of the time. When the sentence is death, then the state should be confident that the verdict was correct. Any information that creates doubt regarding the verdict ineeds to be investigated to ensure that execution is merited.
This is why I am not a fan of capital punishment. A wrong verdict that takes away 20 years or so of a person’s life is bad enough but if the state discovers they were wrong, then the person, at least, has his life. Death can not be undone. Missouri seemed more concerned about carrying out the sentence than ensuring that the verdict was correct.
