Strong | But it deters future killings, study says

I have a distinct
recollection of one of my first lectures at the University of Pennsylvania Law
School. Stephen Schulhofer, a brilliant academic (he's now at NYU) who looked
as if he'd responded to Central Casting's call for a liberal, was leading a
discussion of the death penalty - and he was having difficulty finding anyone
to speak in support.
I still had hair back then,
admittedly not much, and perhaps my close-cropped coif was just the invitation
Schulhofer needed to include me as a participant as he looked for a contrarian.
I took the bait and weighed in.
"But do you think it's
a deterrent, Mr. Smerconish?" he pressed. When I responded affirmatively, my
classmates literally hissed their disapproval.
For me, the only thing that
has changed relative to the death penalty in the intervening 20 years is that
I've grown accustomed to the public ridicule that often accompanies my view. I
still think it's a deterrent, and my opinion is emboldened by a recent analysis
of execution and homicide data published in the Wall Street Journal.
Roy Adler and Michael
Summers, both professors at Pepperdine University, have recently analyzed the
relationship between the number of U.S. executions by year and the number of
murders in the year thereafter for 1979-2004. They relied on raw data supplied
by the Death Penalty Information Center and the FBI.
They have documented a
relationship between capital punishment and the future rate of homicide. When
executions leveled off, the professors found, murders increased. And when
executions increased, the number of people murdered dropped off. In a
year-by-year analysis, Adler and Summers found that each execution was associated
with 74 fewer murders the following year.
That's a stunning statistic,
but as I have already learned, not one that will necessarily sway death-penalty
opponents. When I shared the data last week with actor, M.A.S.H. TV star, and death-penalty opponent Mike Farrell, he
dismissed it as "peddled" and part of an agenda: "It's a claim,
it's a typical claim that comes up periodically, and it's been refuted
generally. As is always the case, this hard data is analyzed by people that
have a bias one way or the other."
But one of the Pepperdine
professors assured me they brought no agenda to the table.
"The morality of the
issue is something for someone else to argue," Adler, himself a Fulbright
professor, told me this month. "We're just simply presenting the data and
lifting the veil that says, 'There's no deterrent effect, therefore . . . '
Well, there is, and it's about 74 to 1. And other people can argue moral
grounds on either side."
Based on their analysis,
Adler and Summers properly recast the issue that confronts society when
deciding whether to implement the death penalty. The question is not whether to
spare the life of the convicted, but rather, whether to spare the lives of 74
innocents in the year that follows.
"Our intent was to open
this up to a dialogue. The ratio is not 'save a life or not;' it's 'save this
life or save dozens of others next year.' And that's a much more difficult
moral dilemma that deserves wide discussion, I think," Adler told me.
My interview with Adler and
review of his work with Summers reminded me of a similar body of work conducted
in the 1980s by a then-Auburn University criminology professor named Steven
Stack. Now a professor at Wayne State University, Stack sought to answer a more
specific question: Do well-publicized executions deter future homicides?
Because if the public is unaware of an execution, Stack argued, its deterrent
effect cannot be calculated.
Stack targeted 16 execution
cases between 1950 and 1980 that met his criterion for "nationally
publicized." His analysis led him to conclude that approximately 30 fewer
homicides are committed in the month that follows a publicized execution story.
When I caught up with Stack
last week, he told me his work has withstood the test of time and that he was
looking forward to publishing an update that is currently being circulated for
peer review. When I told him his findings were not as significant as those of
Adler and Summers, he appropriately quipped, "I suppose it's especially
significant if you're one of those 30 people who would've been killed
otherwise."
Of course, what put the
issue of crime and capital punishment on my mind was the violence against
Philadelphia police officers, specifically the murder of Officer Chuck Cassidy.
How ironic that one day after the Philadelphia District Attorney's Office
decided not to pursue death for Solomon Montgomery (who pleaded guilty to the
brutal killing of Officer Gary Skerski), the execution of Officer Cassidy
rocked the city anew.
You can't blame the D.A.'s
Office or the Skerski family for not pressing for Montgomery's execution. No
doubt they were reflecting that in one month, the Faulkner family will mark the
26-year anniversary of the night Mumia Abu-Jamal murdered Officer Danny
Faulkner - a death-penalty case with no end in sight. Soon, the Cassidy family
may have to make its wishes known relative to John Lewis, given his confession
Tuesday to the murder of Chuck Cassidy.
Meanwhile, the U.S. Supreme
Court has instituted a de facto death-penalty moratorium. For all practical
purposes, capital punishment is on life support.
Too bad.
Because while the academics
tabulate their evidence suggesting that the death penalty deters crime, what I
told my law professor at Penn two decades ago remains incontrovertible. When he
asked me if I thought the death penalty was a deterrent, I borrowed a line I'd
heard Frank Rizzo once deliver.
"Professor," I
said, "I know it deters at least one person at a time."
