The death penalty deters crime.  The state has a responsibility to protect the lives of innocent citizens, and enacting the death penalty may save lives by reducing the rate of violent crime. The reasoning here is simple- fear of execution can play a powerful motivating role in convincing potential murderers not to carry out their acts. While the prospect of life in prison may be frightening, surely death is a more daunting prospect. Thus, the risk of execution can change the cost-benefit calculus in the mind of murderers-to be so that the act is no longer worthwhile for them1. Numerous studies support the deterrent effect of the death penalty. A 1985 study by Stephen K. Layson at the University of North Carolina showed that a single execution deters 18 murders. Another influential study, which looked at over 3,054 counties over two decades, further found support for the claim that murder rates tend to fall as executions rise2. On top of this, there are ways to make the death penalty an even more effective deterrent than it is today. For instance, reducing the wait time on death row prior to execution can dramatically increase its deterrent effect in the United States1. In short, the death penalty can- and does- save the lives of innocent people. 1 Muhlhausen, David. "The Death Penalty Deters Crime and Saves Lives," August 28,2007.
