Defenders of capital punishment are always quick to argue that capital punishment is not a deterrent. Ernest van den Haag, a law Professor at Fordham University who has studied the question of deterrence closely, wrote: “Even though statistical demonstrations are not conclusive, and perhaps cannot be, capital punishment is likely to deter more than other punishments because people fear death more than anything else. They fear most death deliberately inflicted by law and scheduled by the courts.’’ I agree.
