The Kentucky Commission on Human Rights voted unanimously last week to recommend that the state abolish the death penalty. There is every reason for Kentucky to take the advice and become the 18th state to prohibit capital punishment.

The death penalty in Kentucky is colossally unfair, costly and riddled with constitutional error. From 1976 through last year, of the 78 people sentenced to death in the state, 50 had their sentences overturned on appeal, with 15 of those for prosecutorial mistakes or misconduct.

In December, a report conducted by the American Bar Association based on a two-year review by a team of lawyers, professors and former members of the State Supreme Court found enormous problems with the state’s capital system.

Kentucky’s laws and procedures, the report said, failed to “protect the innocent, convict the guilty and ensure the fair and efficient enforcement of criminal law in death penalty cases.”
