INCREASED RELIANCE ON PRISONS: Concerning the fifteenfold increase in drug-crime prisoners, see Ilyana Kuziemko and Steven D. Levitt, “An Empirical Analysis of Imprisoning Drug Offenders,” Journal of Public Economics 88, nos.

9–10 (2004), pp. 2043–66. / 123 What if we just turn all the prisoners loose? See William Nagel, “On Behalf of a Moratorium on Prison Construction,” Crime and Delinquency 23 (1977), pp. 152–74. / 123 “Apparently, it takes a Ph.D….”: See John J. DiIulio Jr., “Arresting Ideas: Tougher Law Enforcement Is Driving Down Urban Crime,” Policy Review, no. 75 (Fall 1995).

CAPITAL PUNISHMENT: For a full report on New York State’s failure to execute a single criminal, see “Capital Punishment in New York State: Statistics from Eight Years of Representation, 1995–2003” (New York: The Capital Defender Office, August 2003), which is available as of this writing at nycdo.org/8yr.html. More recently, New York’s Court of Appeals found the death penalty itself unconstitutional, effectively halting all executions. / 125

Executing 1 criminal translates into 7 fewer homicides: See Isaac Ehrlich, “The Deterrent Effect of Capital Punishment: A Question of Life and Death,”

American Economic Review 65 (1975), pp. 397–417; and Isaac Ehrlich, “Capital Punishment and Deterrence: Some Further Thoughts and Evidence,” Journal of Political Economy 85 (1977), pp. 741–88. / 125 “I no longer shall tinker with the machinery of death”: From Justice Harry A. Blackmun’s dissenting opinion in a 1994 Supreme Court decision denying review of a Texas death-penalty case: Callins v. Collins, 510 U.S. 1141(1994); cited in Congressional Quarterly Researcher 5, no. 9 (March 10,1995). It should be noted that American juries also seem to have lost their appetite for the death penalty—in part, it seems, because of the frequency with which innocent people have been executed in recent years or exonerated while on death row. During the 1990s, an average of 290 criminals were given the death sentence each year; in the first four years of the 2000s, that number had dropped to 174. See Adam Liptak, “Fewer Death Sentences Being Imposed in U.S.,” New York Times, September 15, 2004.

THE “AGING POPULATION” THEORY: See Steven D. Levitt, “The Limited Role of Changing Age Structure in Explaining Aggregate Crime Rates,”

Criminology 37, no. 3 (1999), pp. 581–99. Although the aging theory has by now been widely discounted, learned experts continue to float it; see Matthew L.

Wald, “Most Crimes of Violence and Property Hover at 30-Year Low,” New York Times, September 13, 2004, in which Lawrence A. Greenfield, director of the Bureau of Justice Statistics, says, “There is probably no single factor explanation for why the crime rates have been going down all these years and are now at the lowest level since we started measuring them in 1973. It probably has to do with demographics, and it probably has to do with having a lot of very high-rate offenders behind bars.” / 135 “There lurks a cloud”: See James Q. Wilson,
