A new study by North Carolina's Center for Death Penalty Litigation examines the financial and human costs of cases in which, "prosecutors sought the death penalty despite a clear lack of evidence, resulting in acquittal or dismissal of charges." The report found 56 such cases in North Carolina since 1989, in which innocent people spent a total of 112 years spent in jail, with $2.4 million spent in defense costs alone in these weak death penalty cases. The authors compare these cases to those in which people were wrongfully convicted and sent to death row, saying, "We found cases in which state actors hid exculpatory evidence, relied on junk science, and pressured witnesses to implicate suspects. In several cases, there was no physical evidence and charges were based solely on the testimony of highly unreliable witnesses, such as jail inmates, co-defendants who were given lighter sentences in return for cooperation, and paid informants. Reliance on such witnesses was a factor in more than 60 percent of the cases we studied." In addition to the clear-cut time and financial costs, the study also describes the effects of wrongful prosecutions on the defendants: "In addition to leaving many in financial ruin, the state does not even do these exonorees the favor of clearing their criminal histories. They must request a court order to expunge their criminal records, an expensive and lengthy process. Those who were already living at the margins of society often struggled to find jobs, and some fell into homelessness after they were released from jail." The authors conclude by contrasting the intended use of the death penalty with their findings: "A punishment as serious as execution should be pursued only in the most ironclad cases: those with the strongest evidence of guilt and in which the circumstances of the crime make the defendant more culpable than most—the 'worst of the worst.' Yet, the reality is entirely different. This report uncovers a system in which the threat of execution is used in the majority of cases, regardless of the strength of the evidence."
