In addition, criminals have admitted, in thousands of fully documented cases, that the death penalty was the specific threat which deterred them from committing murder (Pro-Death Penalty, 2014).
The opponents of capital punishment claim that the death penalty has caused and can cause the execution of innocent people.
While many countries have outlawed it, some (like the United States) practice capital punishment on the state level.
However, according to the supporters, no evidence indicates that innocent people have been executed.
Upon reviewing 23 years of capital sentences, a Wall Street Journal study indicated that they were unable to find a single case in which an innocent person was executed (Eddlem, 2002).
Capital punishment and the practice of the death penalty is an issue that is passionately debated in the United States.
Opponents of the death penalty claim that capital punishment is unnecessary since a life sentence accomplishes the same objective.
