"the data is consistent with state-level data in the united states, which has repeatedly shown lower murder rates in states that do not have the death penalty than in states that do and that the presence or absence of the death penalty does not appear to affect murder trends"
asıl olarak sorunu cevaplayan kısmı alıntılıyorum:
"q: doesn't the death penalty deter crime, especially murder? a: no, there is no credible evidence that the death penalty deters crime more effectively than long terms of imprisonment. states that have death penalty laws do not have lower crime rates or murder rates than states without such laws. and states that have abolished capital punishment show no significant changes in either crime or murder rates."
