The death penalty reduces murder rates through deterrence more than long prison sentences do.

the verdict
INSUFFICIENT LEANING
Recorded sources
0 sources for · 3 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the death penalty reduces murder rates through deterrence more than long prison sentences do?

Unclear. Several studies find no evidence that death penalty statutes or executions deter murders, but none of the retrieved items directly compares the deterrent effect of capital punishment with that of long prison sentences.
