Introduction
Capital punishment, also referred to as the death penalty, is the judicially ordered execution of a prisoner as a punishment for a serious crime, often called a capital offense or a capital crime. Some jurisdictions that practice capital punishment restrict its use to a small number of criminal offences, principally treason and murder. Prisoners who have been sentenced to death are usually kept segregated from other prisoners in a special part of the prison pending their execution. In some places this segregated area is known as "Death Row."
Historically and still today under certain systems of law—the death penalty was applied to a wider range of offenses, including robbery or theft. It has also been frequently used by the military for crimes including looting, insubordination, and mutiny.
Significant Researches
A Duke University study found... "The death penalty costs North Carolina $2.16 million per execution over the costs of a non-death penalty murder case with a sentence of imprisonment for life."
"The death penalty costs California $90 million annually beyond the ordinary costs of the justice system - $78 million of that total is incurred at the trial level." (Sacramento Bee)
"A 1991 study of the Texas criminal justice system estimated the cost of appealing capital murder at $2,316,655. In contrast, the cost of housing a prisoner in a Texas maximum security prison single cell for 40 years is estimated at $750,000." (Robert M. Baird and Stuart E. Rosenbaum)
"Florida spent an estimated $57 million on the death penalty from 1973 to 1988 to achieve 18 executions - that is an average of $3.2 million per execution." (Miami Herald)
"Florida calculated that each execution there costs some $3.18 million. If incarceration is estimated to cost $17000/year, a comparable statistic for life in prison of 40 years would be $680,000.......
