Innocence

The death penalty carries the inherent risk of executing an innocent person. Since 1973, at least 200 people who were wrongly convicted and sentenced to death in the U.S. have been exonerated.

The Most Common Causes of Wrongful Death Penalty Convictions: Official Misconduct and Perjury or False Accusation

Overview

Given the fal­li­bil­i­ty of human judg­ment, there has always been the dan­ger that an exe­cu­tion could result in the killing of an inno­cent per­son. Nevertheless, when the U.S. Supreme Court held the admin­is­tra­tion of the death penal­ty to be uncon­sti­tu­tion­al in 1972, there was bare­ly any men­tion of the issue of inno­cence in the nine opin­ions issued. Although mis­takes were sure­ly made in the past, the assump­tion pre­vailed that such cas­es were few and far between. Almost every­one on death row was surely guilty.

However, as fed­er­al courts began to more thor­ough­ly review whether state crim­i­nal defen­dants were afford­ed their guar­an­teed rights to due process, errors and offi­cial mis­con­duct began to reg­u­lar­ly appear, requir­ing retri­als. When defen­dants were now afford­ed more expe­ri­enced coun­sel, with fair­ly select­ed juries, and were grant­ed access to sci­en­tif­ic test­ing, some were acquit­ted and released. Since 1973, 200 for­mer death-row pris­on­ers have been exon­er­at­ed of all charges relat­ed to the wrong­ful con­vic­tions that had put them on death row.
 

At Issue

It is now clear that inno­cent defen­dants will be con­vict­ed and sen­tenced to death with some reg­u­lar­i­ty as long as the death penal­ty exists. It is unlike­ly that the appeals process — which is main­ly focused on legal errors and not on fac­tu­al deter­mi­na­tions — will catch all the mis­takes. Reforms have been begrudg­ing­ly imple­ment­ed, increas­ing both the costs and the time that the death penal­ty con­sumes, but have not been suf­fi­cient to over­come human error. The pop­u­lar­i­ty and use of cap­i­tal pun­ish­ment have rapid­ly declined as the inno­cence issue has gained atten­tion. The remain­ing ques­tion is how many inno­cent lives are worth sac­ri­fic­ing to pre­serve this punishment.

What DPI Offers

DPI has led the way in high­light­ing the issue of inno­cence. Its list of exon­er­at­ed indi­vid­u­als is pre­sent­ed in a search­able data­base, with links to more com­plete descrip­tions of each case. DPI has issued a series of reports on this issue, col­lect­ing the lat­est infor­ma­tion on why so many mis­takes occur. It also fol­lows the relat­ed ques­tions of whether inno­cent indi­vid­u­als have already been exe­cut­ed and whether some defen­dants are in fact inno­cent, despite not being com­plete­ly exon­er­at­ed in the eyes of the law.
