It should be noted that, contrary to popular belief, there was not a blanket ban on legal abortion before the early 1970s. While closely regulated, the procedure was legal in various circumstances, such as when the life or health of the mother was at risk.Read more at location 1900
In fact, in 1970-1973, when abortion was “legal” in five states but “banned” in the rest, some of the “banned” states had similar or even higher rates of legal abortion than in the “legal” states.Read more at location 1902

Consequently, both men and women tend to be more reluctant to engage in casual sex, especially unprotected sex, when abortion is illegal.Read more at location 1925
Indeed, multiple studies have shown that legalized abortion, by raising the rate of unprotected premarital sex, increases the number of unplanned births, even outweighing the reduction in unplanned births due to abortion.Read more at location 1932
From the early 1970s, when abortion was liberalized, through the late 1980s, there was a tremendous increase in the rate of out-of-wedlock births, rising from an average of 5 percent in 1965-69 to over 16 percent twenty years later (1985-1989). For African Americans, the numbers jumped from 35 percent to 62 percent.Read more at location 1934
The evidence shows that the greater availability of abortion largely ended “shot-gun” marriages, where men reacted to an unplanned pregnancy by doing the honorable thing—marrying their partner. But with abortion as a legal option, men became more reluctant to stay with a woman who refuses to have one.Read more at location 1943
With work and other demands on their time, single parents, no matter how “wanted” their child may be, tend to devote less attention to their children than do married couples;Read more at location 1952
The children of unmarried, cohabitating couples also receive less care and attention than married couples’ children.Read more at location 1955
Children raised outside of wedlock experience a higher rate of social problems in nearly every area than children of married couples. Unsurprisingly, children from unmarried families are also more likely to grow up to commit crimes.Read more at location 1961
So the opposing arguments are clear—one stresses that abortion eliminates “unwanted” children, while the other emphasizes that abortion increases out-of-wedlock births. Both effects, conceivably, could be occurring at the same time. The question is: which one has the bigger impact on crime?Read more at location 1965

“abortion decreases crime” argument encounters further inconsistencies when we compare U.S. crime and abortion trends to those in Canada. While crime rates in both the United States and Canada began declining at the same time, Canada liberalized its abortion laws much later than the U.S. did.Read more at location 1987
In sum, even if one effect of abortion were to lower crime by culling out “unwanted” children—a conclusion derived from flawed statistics—the effect is greatly outweighed by the rise in crime that abortion causes by increasing out-of-wedlock births.Read more at location 1993
However this effect—both among African Americans and the population at large—was more than offset by other factors that caused the massive drop in crime of the 1990s.Read more at location 1998
What Increased Crime? Part II Affirmative Action Hiring in the Police ForceRead more at location 2001
Many police departments implemented affirmative action policies in the 1990s, just as the crime rate was entering a steep decline. But a close study reveals that crime fell despite these programs, not because of them.Read more at location 2003
Affirmative action policies have sought to transform traditional police hiring standards that rely on intelligence exams, strength tests, and criminal background checks. Because, on average, women are less likely to pass strength tests than are males, while African Americans have lower passing rates on intelligence exams and criminal background checks than whites, many police departments adopted new standards in an effort to increase minority hiring.Read more at location 2017
In Chicago, the city paid $5.1 million for consultants to develop “unbiased” exams, only to have unacceptable numbers of minorities once again fail the tests.Read more at location 2041
The risk inherent in hiring weaker officers is demonstrated by the case of Brian Nichols, a thirty-three-year-old, 196-pound rape defendant. In an Atlanta courthouse, Nichols overpowered his guard, seized her gun, and used it to kill a judge, a court reporter, a police officer, and a federal agent.Read more at location 2055
The results were dramatic: crime rates jumped in cities using affirmative action policies that lowered testing standards. Interestingly, however, the use of norming had much less harmful results.Read more at location 2066
However, my study also found that lowered strength standards made female officers more vulnerable to assault and less able to control resisting suspects by themselves.Read more at location 2081

What Decreased Crime? Part I The Death PenaltyRead more at location 2093
Although it would be nice and neat if we could identify a single element as the solution, the truth is that numerous factors combined to drive down crime. One of the most important of these was the Supreme Court’s 1976 decision to rescind the ban on the death penalty. Three-quarters of the states soon re-imposed the death penalty, though it wasn’t until the early 1990s that significant numbers of executions began occurring again.Read more at location 2095
the states that reinstituted the death penalty had about a 38 percent larger drop in murder rates by 1998.Read more at location 2126
Isaac Ehrlich, then a young assistant professor at the University of Chicago, conducted path-breaking research showing that each execution deterred as many as twenty to twenty-four murders. 68 His findings, however, were anathema in liberal academia. His conclusions were roundly condemned, and Ehrlich was denied tenure at the University of Chicago.Read more at location 2134
his contentious findings sparked a good deal of new research into the effectiveness of capital punishment, including a special panel convened by the National Academy of Sciences. The panel came to the curious conclusion that greater penalties generally fail to deter criminals.Read more at location 2137
executions were relatively rare until the 1990s, when execution rates spiked dramatically. This elicited a flood of new research on capital punishment. Moreover, the new studies drew upon much more extensive data than had previously been available, allowing researchers to study crime rates over many years and across every state.Read more at location 2142
The fresh studies resurrected Ehrlich’s earlier conclusions that the death penalty greatly deters murder. The vast majority of recent scholarly research confirms this deterrent effect.70 Generally, the studies found that each execution saved the lives of roughly fifteen to eighteen potential murder victims.71 Overall, the rise in executions during the 1990s accounts for about 12 to 14 percent of the overall drop in murders.Read more at location 2146
One particular kind of crime where the death penalty shows no significant deterrent effect is multiple victim public shootings.Read more at location 2153
The death penalty has a beneficial effect even beyond deterring murders. Because capital punishment can be imposed if a victim dies in the commission of a rape, robbery, or aggravated assault, statistics show the death penalty also acts as a deterrent to these crimes as well.Read more at location 2157
utilizing the death penalty too broadly can create some perverse incentives. Suppose the death penalty is used against robbers and rapists. These criminals would then become more determined to kill their victims and any potential witnessesRead more at location 2161

Professor Blumstein said...that it has become increasingly clear from statistical research that “there is no reason that the prison count and the crime rate have to be consistent.” The crime rate measures the amount of crime people are suffering from, he said, while the prison count is a measure of how severely society chooses to deal with crime,Read more at location 2177

This holds true whether the criminal is armed or unarmed and regardless of the location of the attack.Read more at location 2231
During the 1990s, for example, assault victims who used a gun for self-protection were injured 3.6 percent of the time.

Some analysts, however, continue to dispute the deterrent effect of concealed handguns. But even much of the research done by these supposed critics ends up showing substantial safety benefits associated with concealed weapons. For instance, in arguing that more guns create more crime, Mark Duggan provided thirty estimates of the impact of right-to-carry laws.96 But after correcting for four typing mistakes, sixteen of his thirty estimates actually show statistically significant drops in crime, while only one shows a significant increase.Read more at location 2247

Big Penalties for Small Environmental Crimes: A Surprisingly Good PolicyRead more at location 2460
Traditionally, those who committed major environmental crimes—such as a massive oil spill from a tanker running aground—had to pay fines equivalent to the amount of the damages. In contrast, for minor environmental crimes—for example, dumping a barrelful of waste off the side of a ship—the fines were many times greater than the damage estimates. The commission reversed this relationship so that penalties for the more serious crimes became many times bigger than the damages. While the new regulations seem logical, there was a sound reason for the earlier policy. A major oil spill is something that is nearly impossible to hide—we will know with near-certainty that the crime occurred and which ship was responsible.
