Capital punishment

Is it righteous or not? Or, effective or not? You can find a nice summary (as always) in Wikipedia (http://en.wikipedia.org/wiki/Capital_punishment_debate). Amnesty International also has a webpage containing various material (intherye:국제 앰네스티 사형 QnA 한글 번역).

Deterrence

• http://www.freakonomics.com/blog/2007/06/11/does-the-death-penalty-really-reduce-crime/

  Analyses of data stretching farther back in time, when there were many more executions and thus more opportunities to test the hypothesis, are far less charitable to death penalty advocates. On top of that, as we wrote in Freakonomics, if you do back-of-the-envelope calculations, it becomes clear that no rational criminal should be deterred by the death penalty, since the punishment is too distant and too unlikely to merit much attention. As such, economists who argue that the death penalty works are put in the uncomfortable position of having to argue that criminals are irrationally overreacting when they are deterred by it.

• sovidence:사형의 살인 감소 효과

  사형이 살인을 줄인다는 초기 연구 결과에 대해, 종합 연구(예를 들면 Donohue & Wolfers 2005)들은 방법론에 따라 사형의 살인감소 효과가 없다가도 있어지는 등 결론이 완전히 달라지기 때문에 아무리 좋게 봐줘도 “논란이 있다” 정도라고 주장하고 있다. … 이 주제는 방법론에 따라 워낙 결과의 변동이 심하기 때문에 아무리 연구 방법론이 개선되었더라도 한 가지 연구로 결론을 내릴 수는 없지만, 베커가 옛날에 얘기했던, 처벌이 너무 심하면 (즉, 사형을 당할 것 같으면) 잠재적 증인을 살려두기 보다는 죽여 없애는게 처벌받지 않은 확률을 높인다는 식의 논리 (즉, 사형제가 오히려 살인을 늘린다는 주장) 는 그리 지지되지 않는 듯.

• Current Research Not Sufficient to Assess Deterrent Effect of the Death Penalty

• Deterrence and the Death Penalty

  This new report from the Committee on Law and Justice concludes that research to date on the effect of capital punishment on homicide rates is not useful in determining whether the death penalty increases, decreases, or has no effect on these rates. The key question is whether capital punishment is less or more effective as a deterrent than alternative punishments, such as a life sentence without the possibility of parole. Yet none of the research that has been done accounted for the possible effect of noncapital punishments on homicide rates.
