Going about the business of law enforcement produces a few problems, as John Paul Stevens
reveals in his review of
The Collapse of American Criminal Justice by William J. Stuntz:
Ironically, during an age of increasing protection for civil rights, discrimination against both black suspects and black victims of crime steadily increased. Stuntz attributes this development, in part, to the expansion of prosecutorial and police discretion—in his view, “discretion and discrimination travel together.” For example, the discretionary authority to enforce posted speed limits has enabled state troopers to be selectively severe in making arrests, and to use those arrests to justify searches for evidence of drug offenses. While Stuntz does not suggest that such discriminatory enforcement of traffic laws is itself a national crisis, it provides one illustration of the negative effects of excessive enforcement discretion.
The result, Stuntz writes, has been a serious disadvantage to African-Americans in their encounters with the American criminal justice system. While only 10 percent of the adult black population uses illegal drugs, as does a roughly equal percentage—9 percent—of the adult white population, blacks are nine times more likely than whites to serve prison sentences for drug crimes. “And the same system that discriminates against black drug defendants also discriminates against black victims of criminal violence.” As “suburban voters, for whom crime is usually a minor issue,” have come to “exercise more power over urban criminal justice than in the past,” police protection against violent felonies has disproportionately extended to suburban neighborhoods rather than the urban centers where more black individuals reside.
