Executing an innocent person — even a merely potentially innocent person — is surely the the depth of evil. This execution, going forward tomorrow, combines so many kinds of moral failure it staggers the imagination. (See Mark Keliman’s commentary here.) My stomach turns at the knowledge that the United States has an “Anti-terrorism and Effective Death Penalty Act” — the language combines Orwell’s vision of authoritarian corruption with Kafka’s sense of the nonchalant use of power in a perfect poem of moral darkness. Update: Davis’ life spared, but he still faces life in prison; if, as Mark Kleiman points out, he was spared because he is innocent of the crime for which he was convicted, he does not belong in prison.
