Death Penalty Deterrence myth

The Dallas Morning News had an editorial trying to outlay why the death penalty is a miserable failure as a deterrence. What the news media refuses to understand, it is not about deterrence, but justice. It is getting even, retribution, and closure for the victim's family. Nowhere in the editorial was the impact upon the victim's families mentioned. The media is attempting to influence the debate by twisting it. During the debate about the death penalty has the media ever evenly outlined the victim's families take on the subject? Nor has the media ever tried to examine the discussion from a point of administering justice
