EARLIER THIS sum­mer, we pub­lished a study of the death penal­ty in this coun­try. Our find­ings were dis­turb­ing and have pro­voked strong reac­tions. Two months lat­er, it is time to look at some of those reac­tions, clar­i­fy mis­un­der­stand­ings and under­line our cen­tral claim that the death penal­ty sys­tem is deeply flawed.

Looking at thou­sands of death ver­dicts reviewed by courts in 34 states over 23 years, we found that near­ly sev­en in 10 were thrown out for seri­ous error, requir­ing 2,370 retri­als. For cas­es whose out­comes are known, an aston­ish­ing 82% of retried death row inmates turned out not to deserve the death penal­ty; 7% were not guilty. The process took nine years on aver­age. Put sim­ply, most death ver­dicts are too flawed to car­ry out, and most flawed ones are scrapped for good. One in 20 death row inmates is lat­er found not guilty.

Some crit­i­cisms of our study mis­state our meth­ods and find­ings. For exam­ple, we did not count whole­sale rever­sals in 1976, when the Supreme Court void­ed many states’ cap­i­tal statutes, but only those in states with valid statutes. We did not count rever­sals of ver­dicts that a high­er court reinstated.

Liberal fed­er­al judges are not respon­si­ble for rever­sals: 90% were by elect­ed state judges. Most fed­er­al rever­sals occurred when a major­i­ty of judges were Reagan and Bush appointees.

We did not manip­u­late sta­tis­tics because we oppose the death penal­ty. We count­ed out­comes of all death sen­tences, ask­ing a sim­ple ques­tion: Was the ver­dict approved, or thrown out by the courts?

One cri­tique focused on a sin­gle typo­graph­i­cal error mis­re­port­ing one Florida retri­al out­come. But dig­ging deep­er for Florida data showed that we under­count­ed Florida rever­sals. This indi­cates that the error rates we report are like­ly con­ser­v­a­tive: If no errors are found, pris­on­ers are exe­cut­ed. Their cas­es are easy to track. It’s hard­er to find rever­sals that release peo­ple from death row.

Significant errors
Errors lead­ing to rever­sal are not tech­ni­cal­i­ties.” Virtually none were police seizures of reli­able evi­dence. Where known, 80% were egre­gious­ly incom­pe­tent lawyer­ing, police sup­pres­sion of evi­dence of inno­cence, faulty jury instruc­tions and biased judges and jurors ¯ errors that courts and stud­ies have found are like­ly to put the wrong peo­ple on death row.

Some read­ers ask valid ques­tions. Capital cas­es can go through three stages of court review. Our data on how often retri­al out­comes change cov­er ver­dicts thrown out at the sec­ond stage. What can be said about the oth­er stages? The first lev­el of court review catch­es the most glar­ing errors, so these rever­sals may lead to more, not few­er, changed out­comes. The third stage is sim­i­lar to the sec­ond, so their retri­al out­comes may be similar.

It took time to doc­u­ment all such rever­sals that occurred between 1973 and 1995. Have things changed in the mean­time? There is evi­dence that our sys­tem of find­ing and cur­ing errors has weak­ened, but there is no rea­son to think that cas­es reviewed in 1999 were less error prone than those in 1995.

Finally, our crit­ics say that focus­ing on high rates of seri­ous­ly flawed cap­i­tal ver­dicts (1) avoids the cru­cial issue of the moral­i­ty of cap­i­tal pun­ish­ment, (2) shows that the sys­tem works or (3) is irrel­e­vant absent proof that inno­cent peo­ple are being executed.

Our study aims to put aside moral dilem­mas that can’t be solved and ask a ques­tion man­agers, con­sumers and cit­i­zens answer every day: What do error rates say about whether a sys­tem does what it’s sup­posed to do and avoids seri­ous risk? If 68% of an air­line’s planes fail inspec­tion and 82% sent for repairs are per­ma­nent­ly ground­ed, the mean­ing is clear. The sys­tem is bro­ken. No one would say, The air­line works. It’s good at catch­ing mis­takes.” And no one would fly the few planes that pass inspec­tion ¯ even though no one has yet turned up dead. The risk is too high.

Our cur­rent death penal­ty sys­tem does not work” when two of three death ver­dicts are too flawed to serve their pur­pose, when most can’t be sal­vaged and when the cost of each failed ver­dict is mea­sured in hun­dreds of thou­sands of tax dol­lars, decades of time and untold anguish for vic­tims needing closure.

Nor can death ver­dicts get­ting through the sys­tem be trust­ed. High error rates mean that all ver­dicts are sus­pect. They also over­whelm the review sys­tem. Forty per­cent of ver­dicts pass­ing the first two judi­cial check­points prove flawed at the last one. What would a fourth check find?

Chronically high cap­i­tal error rates are the warn­ing light in the cock­pit. We ignore them at our peril.
