23. I also included a tenth variable that examined the percentage of the adult population that was in prison, but there were sufficient theoretical objections to including this that I have decided not to report these results in the text. The major theoretical problem is that this variable is a "stock" while the crime rate is a "flow." In other words, the prison population is created by the number of people who are convicted and sentenced over many years and not just how harsh the current sentences are. In fact, if tough sentencing in the past makes it more likely that current criminals will not be sentenced to prison terms as long as those of past criminals (e.g., because of a takeover of the prison system by the courts), it is possible that there might even be a negative relationship between the prison population and the current toughness of the system. The bottom line is that past punishment is only roughly related to current punishment, particularly when average state differences are already being taken into account through fixed effects and when regional yearly fixed effects have also been added.
24. In a powerful piece, Isaac Ehrlich and Zhiqiang Liu show that classic economics papers concerning the law of demand, production theory, and investment theory would fail this test (Isaac Ehrlich and Zhiqiang Liu, "Sensitivity Analyses of the Deterrence Hypothesis: Let's Keep the Econ in Econometrics," Journal of Law and Economics 42 [Apr. 1999]: 455—88). Because of this strong bias toward not finding "true" relationships, Learner and McManus have dropped off the 10 percent most extreme values on both ends of their estimates when they have reported their results. Yet even this does not protect most studies from having their results determined to be "fragile" by this test.
25. One problem from excluding the arrest rate was never clearly made in the first edition of this book. The reason using the arrest rate forces some county observations to be dropped is that when the number of crimes is zero, the arrest rate is "undefined." Including counties with zero crime rates biases the results toward not finding an effect because crime rates cannot fall below zero. Since these counties already have a zero crime
296 / NOTES TO PAGES 186-190
rate, the passage of the right-to-carry law can produce no benefit. The more counties with zero crime rates that are included, the more the estimated benefit from the law will move toward zero.
My work with Steve Bronars also examined whether replacing the crime-specific arrest rates with the overall violent-crime or property-crime arrest rates altered the results, and we found that it had no impact on the results. There are few counties which have no violent crimes of any type, so there are few missing observations for the violent-crime arrest rate (Stephen G. Bronars and John R. Lott, Jr., " Criminal Deterrence, Geographic Spillovers, and Right-to-Carry Laws," American Economic Review 88 (May 1998): 475—79).
26. While I find it difficult to believe that anyone would argue that demographic factors are not important in explaining crime rates, I did try a couple of specification tests. Paring the demographic variables down to the percentage of the population that is black, the percentage of the population that is white, the percentage of the population that is male, and the percentage of the population in the six different age classifications leaves the results essentially unchanged. Eliminating the demographic variables entirely reduces the estimated drop in violent-crime rates from right-to-carry laws by at most one percentage point.
27. The way that the county-level data were compiled was changed in 1994. Prior to that time those jurisdictions within a county which provided data for fewer than six months were estimated to have the same offense rates as the rest of the county. From 1994 onward, the imputation method was applied only to counties with less than three months of data. For jurisdictions with at least six months of data prior to 1994 and at least three months of data after that time, the jurisdiction was calculated to have 12/N offenses, where N is the number of months reported.
Because of concerns that this might affect estimates using data after 1993,1 reran the regressions reported in table 9.1 by including a variable for the change in a county's crime rate between 1993 and 1994. This change variable was included for the 1994—1996 observations to account for the relative differences that this change in measurement might have had across different counties. The results are similar to those already reported. The annual difference in the trends in violent-crime rates before and after the passage of a right-to-carry law are —1.4 percent for murder, —2.94 percent for rape, —2.8 percent for robbery, and —3.12 percent for aggravated assault. All the results are significant at better than the .01 percent level with F-tests of 17.36, 83.33, 87.38, and 87.31, respectively.
28. These data draw on research that I am currently conducting with Kevin Cremin. Kevin collected all the data used here on policing policies.
29. "[The] problem-solving effort began essentially as directed patrol operations designed to identify patterns of offending or known offenders and to deploy police to catch the offenders. All gradually evolved into quite different efforts that involved activities other than arrest and agencies other than the police. The attack on burglaries in the housing projects involved surveying tenants, cleaning the projects, creating a multiagency task force to deal with particular problems in the housing projects, and organizing the tenants not only to undertake block watches but also to make demands on city agencies. The attack on thefts from cars eventually involved the inclusion of police officers in the design of new parking lots to make them less vulnerable to theft. The attack on prostitution and robbery involved enhanced code enforcement against hotels and bars that provided the meeting places for prostitutes and their customers as well as decoy operations" (Christopher Slobogin, "Why Liberals Should Chuck the Exclusionary Rule," University of Illinois Law Review 99 (1999): 363.
30. The data on community-oriented policing, problem-oriented policing, and the broken-windows strategy were primarily obtained by using the Westlaw "News" database. For community policing, the search took the form [name of city] & "community policing" & DA(BEF 1/1/1997) & DA(AFT 1/1/1975). For problem-oriented policing, the search
NOTES TO PAGES 190-199/297
took the form ("Problem Solving Policing" or "Problem-Solving Policing" or "Problem Oriented Policing" or "Problem-Oriented Policing") & DA(AFT 1/1/1975) & DA(BEF 1/1/ 1997). Finally, for the broken-windows strategy, the search consisted of "Broken Window" & Crime & DA(AFT 1/1/1975) & DA(BEF 1/1/1997) AND NOT "Broken Windows." Other sources were also investigated. For community policing, the sources included Robert C. Trojanowicz and Hazel A. Harden, "The Status of Contemporary Community Policing Programs," National Center for Community Policing, 1985; Washington State University, Division of Governmental Studies and Services (DGSS), surveys of police administrators conducted at three-year intervals between 1978 and 1994; Anna Sampson, "National Survey of Community Policing Strategies, 1992—93"; and Robert C. Trojanowicz et al., "Community Policing: A Survey of Police Departments in the United States," 1994. However, the only one of these studies which identifies the cities is the 1985 Trojanowicz and Harden study. The authors of the other studies were unwilling to identify the cities in their samples. For the broken-windows strategy, George Kelling's book was also used to identify additional cities (George L. Kelling, Fixing Broken Windows: Restoring Order and Reducing Crime in Our Communities [New York: Free Press, 1998]).

38. To illustrate, let the probability that a single individual is carrying a concealed handgun equal .10. Assume further that there are 10 individuals in a public place. Then the probability that at least one of them is armed is 1 — .9 10 , or about .65.

41. Even so-called smart locks, which are activated by one's fingerprint or by a special ring with a computer, pose several types of risks. With locks activated by fingerprints, a spouse would be unable to use the gun to come to the other person's rescue if the gun were coded for the other person. The person must also correctly position the finger on the fingerprint reader. Small differences in the angle of the finger may leave the gun inoperable even for the designated user.

45. An article in the Journal of the American Medical Association does not control for any other factors but claims that 23 percent of the accidental gun deaths for children under fifteen would have been prevented by these storage rules. In 1996, this would have amounted to thirty-two lives if the laws had been in effect for the entire country. One obvious mistake that this article made was that it made no attempt to account for the normal downward trend in accidental gun deaths that would have continued to at least some extent even without these safe-storage laws. Since no other variables were being controlled for, all of the drop was being attributed to the new law (Cummings et al., "State Gun Safe Storage Laws").

51. Take for example a June 21, 1999, discussion between two people on talk, politics.guns:
"Dutch Courage": hey, did you know Lott's study was funded by a gun manufacturer? I did. That's a little suspicious, don't you think?
"Shawn Wilson": You're right, it was a foundation founded by the owner of a gun company, which is now an ammunition company, and further the foundation has large holdings in this company, and several of the directors of this foundation are men with standing within the company which shares the name. So much for his reputation as an honest scholar and academic reputation, eh?

Bl: "While gun-control activists have criticized Lott's work because it is funded in part through a grant from the Olin Foundation, which was founded by the largest manufacturer of ammunition in the U.S., [Jens] Ludwig argues that the debate about the grant money 'only distracts people. The study fails on its merits.'"
53. This quote is from the Web site of Handgun Control, Inc. (http://www.handgun-control.org/lott.htm). The Violence Policy Center's claim that I believe that "increases in the percent of minority police officers increase crime rates" can be found at http:// www.vpc.org/fact__sht/wholott.htm. Of course, the Violence Policy Center fails to mention the rest of the abstract in question, which points out that the paper (Lott, "Does a Helping Hand Put Others at Risk?") will investigate "whether these increases in crime are due to changes in the quality of all new police officers or just minority officers."
54. The previous footnote provides references for this claim on gun-control Web sites. Similar statements were made by Luis Tolley, the western regional director for Handgun Control, Inc., at a debate that I participated in at Claremont College, and Tom Diaz, an analyst for the Violence Policy Center, has made this claim a couple of times when we appeared on radio shows together.
55. Lott, "Does a Helping Hand Put Others at Risk?"
56. The selective quoting was obviously a well-orchestrated campaign, with newspaper editorials also getting involved in repeating the statements by Handgun Control. Consider the following editorial attack on me: "In May 1998, for instance, he published the following in a police research journal: 'Increasing black officers' share of the police force by one percentage point increases murders by four percent, the violent crimes by
NOTES TO PAGES 203-204/299
seven percent, and property crimes by eight percent.... More black and female officers are also associated with declines in both the arrest and conviction rates'" (Editorial, "A Lott More Guns," St. Louis Post-Dispatch, Mar. 23, 1999, p. B6). They failed to quote some other sentences in this same piece, such as "Not all black officers nor all white officers nor all officers of any other race are of the same quality. Some black officers are undoubtedly better at reducing crime than most potential white officers, and some white officers are probably better than most potential black officers. The question is how to select those officers who will do the best job. There is the possibility that choosing applicants by race or sex could work against hiring the best officers available.... One must be very clear about what is happening, however. The large impact of more black officers indicates that more than just the quality of new minority recruits or new minority promotions are affected. Indeed, changing tests to employ a greater percentage of blacks appears to make it more difficult to screen out lower-quality candidates generally, including whites and other racial groups" (John R. Lott, Jr., "Who Is Really Hurt by Affirmative Action?" Subject to Debate, May 1998, pp. 1, 3).

62. I really don't take most threats very seriously, and I believe that it is just people blowing off steam. The worst threats usually come over the telephone, though I did have some regular writers from Canada who would express the hope that someone would get a gun and kill either me or my family members. The one E-mail threat that was forwarded to me by one of the editors at the University of Chicago Press gives some idea of the types of comments I received:
Pass along the word, to that soulless weasel and absolutely irresponsible chickenshit John M. Lott that he better change his name and get some plastic surgery because his days of [obsceniti
es deleted] of the NRA's [obscenities deleted] will be quickly coming to a crashing close if he keeps trying to pass off unethical, and second rate statistics with his pseudoscience rhetorical sylogisms.
My point—someone is going to become very angered by the view of this imbecile, and is going to get a concealed hand-gun permit and find where he lives and make a point. I won't lose sleep knowing that one more moron is dead, but I feel that he should be warned none-the-less. Also, if John Lott had any integrity he'd make it possible to reach him. Since the little scatmuncher is playing hide and seek by having no-available e-mail adress, whoever reads this please forward this too him. This is not a threat, just a warning.
Sometimes when views of cretins like this are expressed I think "love it or leave it," and man, if our scholars get any stupider and any more immoral than Mr. Lott I'm out of this shit house. I nearly packed my bags.

64. "According to the Federal Bureau of Investigation's Uniform Crime Report, from 1992 to 1997, states which made it easier for citizens to carry concealed handguns had a significantly smaller drop in their crime rates than states which chose not to loosen their conealed weapons laws" (Brian Morton [associate director of communications for Hand-

gun Control and the Center to Prevent Handgun Violence], "John Lott's Gun Research Doesn't Hold Up to Review," Fort Wayne Journal Gazette, Aug. 15, 1999, p. 3C).
Even when others would state that the FBI indeed did not produce these claims, Handgun Control's press release was put on the same footing as my research. Consider the following: "The Center to Prevent Handgun Violence did a 1999 analysis of crime statistics that came to a conclusion opposite of Mr. Lott's, and their study (like his) is open to review by experts in many fields" (Molly Ivins, "More Guns, Less Crime? Are You Sure?" Fort Worth Star-Telegram, Aug. 15, 1999). For clarification, the Center to Prevent Handgun Violence is part of Handgun Control, and Sarah Brady serves as the head of both organizations. Many similar statements were made by the media in Missouri during the debate over the concealed-handgun law.
