Deadly Statistics: A Survey of Crime and
Punishment
By FORD FESSENDEN
New York Times, September 22, 2000, pp. 1
and 19.
In its analysis, The New York Times examined homicide
rates in two groups of states: the 12 states without the
death penalty and the 36 states that passed laws within 10
years of the Supreme Court's 1972 Furman v. Georgia
decision, which overturned all existing death penalty
statutes. (New York and Kansas did not adopt the death
penalty until the 1990's.)
The analysis found that homicide rates have not declined
any more in the states that instituted the death penalty
than in states that did not.
In fact, year after year, homicide rates in states with
death penalties roughly mirrored the rates in states without
capital punishment, with death penalty states 48 percent to
101 percent higher. That trend, criminologists say, provides
evidence that something besides enactment of capital
punishment laws drives homicides.
"It's clear that the states with the death penalty may
want it more because they have more homicides," said Alfred
Blumstein, director of the National Consortium on Violence
Research at Carnegie Mellon University. "But it's not clear
that it does them any good in terms of reducing
homicide."
Even after executions resumed, homicide rates appeared
unaffected, the analysis found. In the 21 states that
carried out their first executions by 1993, homicide rates
declined a collective 5 percent over the four years after
the execution. But rates declined 12 percent in states that
had not had executions in the same years.
The Times also looked at contiguous and demographically
similar states, and found no pattern that differentiated
death penalty states from those without capital punishment.
Massachusetts and Rhode Island, with no death penalty, had
homicide rates of 3.7 per 100,000 and 4.2 per 100,000,
respectively, from 1977 to 1997, while Connecticut, a death
penalty state, had a rate of 4.9 per 100,000.
The survey by The Times is similar to the type of
analysis criminologists used in the years before the Supreme
Court's Furman decision to conclude that state homicide
rates were not affected by death penalty laws. The review by
The Times confirms that those patterns appear to continue
under the new era of capital punishment statutes.
Some researchers still contend that the death penalty has
a measurable deterrent effect. "The statistics involved in
such comparisons have long been recognized as devoid of
scientific merit," Prof. Isaac Ehrlich, of the State
University of New York at Buffalo, said of the analysis by
The Times. He said that if variations like unemployment,
income inequality, likelihood of apprehension and
willingness to use the death penalty are accounted for, the
death penalty shows a significant deterring effect. Most
criminologists, however, discount Professor Ehrlich's
work.
