Defendants' Plea Deals to Avoid Execution Show the Death Penalty Deters Murder and Should Be Kept

The Gist
The author argues that when murderers are caught, they often beg for life in prison to avoid being executed, which shows they fear the death penalty more than anything else. He says this fear deters killings, saves innocent lives, and saves money through plea deals, so the death penalty should be kept.
Conclusion
The death penalty is a powerful deterrent that saves innocent lives and reduces costs, so it should not be eliminated.
Premises
- Many notorious accused murderers (Kohberger, Crusius, Loughner, Rudolph, DeAngelo, Oropeza, and others) pleaded guilty or sought plea deals for life without parole specifically to avoid execution.
- Such behavior shows that murderers fear execution more than life without parole, even when they show little regard for their victims' lives.
- The threat of execution gives prosecutors bargaining leverage, producing plea agreements that avoid expensive trials and appeals (e.g., a capital trial in Oropeza's case could have cost up to $2 million).
- Most peer-reviewed studies estimate that each execution prevents between eight and eighteen murders.
- Public opinion supports capital punishment by more than 2-to-1, with especially strong support among lower-income Americans who face greater exposure to violent crime.
Assumptions
- Defendants' fear of execution once charged and facing trial reflects how potential murderers think before committing a crime.
- Plea-bargaining behavior by those already caught is evidence of general deterrence, not merely of individual self-preservation.
- The cited studies on deterrence are methodologically sound and representative of the research consensus.
- Preventing murders and saving money outweigh moral, procedural, and wrongful-conviction concerns about capital punishment.
- Plea deals produced by the death penalty are net benefits and would not occur at comparable rates under the threat of life without parole alone.
- Public support is relevant to whether the death penalty should be retained.
