Don’t bring back the death sentence.
While I sympathise with those who have lost loved ones through murder and so on. Bringing back the death sentence will not reduce crime. It hasn't reduced the amount of murders in America. Also it is open to abuse and there are innocents in jail who would have been executed if the death penalty was still in use.
Why does this idea matter?
Because of the fear of innocent people being executed for a crime they didn't commit. It is barbaric, the system would be as barbaric as the killer.
