I. Introduction
A new debate over the death penalty is raging in the
United States.1
Until now, the focus of that debate has been the fairness of particular capital
convictions and sentences. This Report addresses a different and broader question: the
reliability-indeed, the bare rationality-of the death penalty system as a whole. It asks
whether the mistakes and miscarriages of justice known to have been made in individual
capital cases2
are isolated, or common? The answer provided by our study of 5,760 capital sentences and
4,578 appeals is that serious error-error substantially undermining the reliability of
capital verdicts- has reached epidemic proportions throughout our death penalty system.
More than two out of every three capital judgments reviewed by the courts during the
23-year study period were found to be seriously flawed.
Americans seem to be of two minds about the death
penalty.3 In
the last several years, executions have risen steeply, reaching a 50-year high.4 Two-thirds of the
public support the penalty.5
Two-thirds support, however, represents a steady decline
from the four-fifths of the population that supported the penalty only six years ago,
leaving support for capital punishment at a 20-year low.6 When life without parole is
proposed as an alternative, support for the penalty drops even more-often below a
majority.7
Grants of executive clemency reached a 20-year high in 1999.8
In 1999 and 2000, Governors, attorneys general and
legislators in Alabama, Arizona, Florida, and Tennessee have fought high-profile campaigns
to speed up and increase the number of executions.9
In the same period, however:
- The Republican Governor of Illinois, with support from a majority of the electorate,
declared a moratorium on executions in the state.10
- The Nebraska Legislature did the same. Although the governor vetoed the legislation, the
Legislature appropriated money for a comprehensive study of the even-handedness of the
state's exercise of capital punishment.11 Similar studies have since been ordered by the Chief
Justice, task forces of both houses of the state legislature and the Governor of Illinois,12 and also the
Governors of Indiana and Maryland and the Attorney General of the United States.13
- Serious campaigns to abolish the death penalty are under way in New Hampshire16 and (with the
support of the Governor and a popular former Republican Senator) in Oregon.17
- The Florida Supreme Court and Mississippi Legislature have recently acted to improve the
quality of counsel in capital cases,18 and bills aiming to do the same and to improve capital
prisoners' access to DNA evidence have been introduced in both houses of the United States
Congress, with bipartisan sponsorship.19
- Observers in the Wall Street Journal, New York Times Magazine, and Salon and on ABC This
Week see "a tectonic shift in the politics of the death penalty ."20 In April 2000
alone, George Will21
and Rev. Pat Robertson-both strong death penalty supporters-expressed doubts about the
manner in which government officials carry out the penalty in the United States, and
Robertson advocated a moratorium on Meet the Press.22
Fueling these competing initiatives are two beliefs about
the death penalty. One is that death sentences move too slowly from imposition to
execution, undermining deterrence and retribution, subjecting our criminal laws and courts
to ridicule, and increasing the agony of victims.23 The other is that death
sentences are fraught with error, causing justice too often to miscarry, and subjecting
innocent and other undeserving defendants-mainly, the poor and racial minorities- to
execution.24
Some observers attribute these seemingly conflicting events
and opinions to "America's schizophrenia-we believe in the death penalty, but shrink
from it as applied."25
These views may not conflict, however, and Americans who hold both may not be irrational.
It may be that capital sentences spend too much time under review and that they are
fraught with disturbing amounts of error. Indeed, it may be that capital sentences spend
so much time under and awaiting judicial review precisely because they are so persistently
and systematically fraught with alarming amounts of error. That is the conclusion to which
we are led by a study of all 4,578 capital sentences that were finally reviewed by state
direct appeal courts, 248 state post-conviction reversals of capital judgments, and all
599 capital sentences that were finally reviewed by federal habeas corpus courts between
1973 and 1995.26
