A new study of Louisiana​’s death penal­ty reports that the state’s cap­i­tal pun­ish­ment sys­tem costs tax­pay­ers at least $15.6 mil­lion a year more than a sys­tem with life with­out parole as the max­i­mum sen­tence. The study by retired New Orleans dis­trict Chief Judge Calvin Johnson (pic­tured, left) and Loyola Law Professor William Quigley (pic­tured, right), released on May 2, 2019, found that Louisiana has spent more than $200 mil­lion on its…

For decades, stud­ies have shown per­sis­tent racial dis­par­i­ties in the admin­is­tra­tion of cap­i­tal pun­ish­ment. Saying ​“death sen­tences are uneven­ly and unfair­ly applied based on race,” California Governor Gavin Newsom on March 13, 2019 imposed a mora­to­ri­um on exe­cu­tions in the state with the nation’s largest death row. Responding to the governor’s mora­to­ri­um In an op-ed for the Los Angeles Times, Stanford psy­chol­o­gy professor…

A new study of four­teen years of Pennsylvania mur­der con­vic­tions has doc­u­ment­ed a sharp decline in coun­ty pros­e­cu­tors’ use of cap­i­tal pun­ish­ment across the Commonwealth. After exam­in­ing the court files of 4,184 mur­der con­vic­tions from 2004 to 2017, the Allentown Morning Call found that Pennsylvania pros­e­cu­tors sought the death penal­ty at more than triple the rate (3.3) at the start of the study peri­od than they did four­teen years lat­er — a drop of more than 70%. In…

Nations that abol­ish the death penal­ty then tend to see their mur­der rates decline, accord­ing to a December 2018 report by the Abdorrahman Boroumand Center, a Washington, DC-based orga­ni­za­tion that pro­motes human rights and democ­ra­cy in Iran. The report exam­ined mur­der rates in 11 coun­tries that have abol­ished cap­i­tal pun­ish­ment, find­ing that ten of those coun­tries expe­ri­enced a decline in mur­der rates in the decade fol­low­ing abo­li­tion. Countries were includ­ed if they met the following…

During his elec­tion cam­paign, Philadelphia District Attorney Larry Krasner described the eco­nom­ic waste­ful­ness of city pros­e­cu­tors’ pur­suit of the death penal­ty as ​“light­ing mon­ey on fire.” A DPIC analy­sis of the out­comes of the more than 200 death sen­tences imposed in the city since 1978 (click here to enlarge image) and the last sev­en years of cap­i­tal pros­e­cu­tion out­comes pro­vides strong sup­port for Krasner’s…

A study of more than three decades of homi­cide arrests sug­gests that racial dis­par­i­ties in arrests and polic­ing prac­tices intro­duce an addi­tion­al lay­er of bias in the appli­ca­tion of the death penal­ty in the United…

Most of the 142 pris­on­ers on North Carolina​’s death row were con­vict­ed under obso­lete and out­dat­ed death-penal­ty laws and would not have been sen­tenced to death if tried today, accord­ing to a new report by the Center for Death Penalty Litigation. The report by the Durham-based defense orga­ni­za­tion, titled Unequal Justice: How Obsolete Laws and Unfair Trials Created North Carolina’s Outsized Death Row, says that near­ly three-quar­ters of the prisoners…

Women face ​“wide­spread dis­crim­i­na­to­ry prac­tices in the cap­i­tal pros­e­cu­tion and deten­tion” in death-penal­ty coun­tries around the world, accord­ing to a new report by the Cornell Center on the Death Penalty Worldwide and the World Coalition Against the Death Penalty. The report, Judged for More Than Her Crime: A Global Overview of Women Facing the Death Penalty—released at the United Nations in Geneva, Switzerland on September 18, 2018 — exam­ines the use…

For the first time in more than a quar­ter cen­tu­ry, few­er than 2,500 pris­on­ers across the United States now face active death sen­tences. According to the lat­est Death Row USA nation­al cen­sus by the NAACP Legal Defense Fund (LDF), released in ear­ly September 2018, 2,743 peo­ple were on death rows in 32 states and the U.S. fed­er­al and mil­i­tary death rows on April 1, 2018. That total includes 249 peo­ple who were pre­vi­ous­ly sen­tenced to death but face the pos­si­bil­i­ty of a cap­i­tal resen­tenc­ing after…
