races, even though they supposedly constituted only 13% of regular drug users. Anti-drug legislation over time has also displayed an apparent racial bias. University of Minnesota Professor and social justice author Michael Tonry writes, "The War on Drugs foreseeably and unnecessarily blighted the lives of hundreds and thousands of young disadvantaged black Americans and undermined decades of effort to improve the life chances of members of the urban black underclass." In 1968, President Lyndon B. Johnson decided that the government needed to make an effort to curtail the social unrest that blanketed the country at the time. He decided to focus his efforts on illegal drug use, an approach that was in line with expert opinion on the subject at the time. In the 1960s, it was believed that at least half of the crime in the U.S. was drug-related, and this number grew as high as 90 percent in the next decade. He created the Reorganization Plan of 1968 which merged the Bureau of Narcotics and the Bureau of Drug Abuse to form the Bureau of Narcotics and Dangerous Drugs within the Department of Justice. The belief during this time about drug use was summarized by journalist Max Lerner in his work America as a Civilization (1957): As a case in point we may take the known fact of the prevalence of reefer and dope addiction in Negro areas. This is essentially explained in terms of poverty, slum living, and broken families, yet it would be easy to show the lack of drug addiction among other ethnic groups where the same conditions apply. Richard Nixon became president in 1969, and did not back away from the anti-drug precedent set by Johnson. Nixon began orchestrating drug raids nationwide to improve his "watchdog" reputation. Lois B. Defleur, a social historian who studied drug arrests during this period in Chicago, stated that, "police administrators indicated they were making the kind of arrests the public wanted". Additionally, some of Nixon's newly created drug enforcement agencies would resort to illegal practices to make arrests as they tried to meet public demand for arrest numbers. From 1972 to 1973, the Office of Drug Abuse and Law Enforcement performed 6,000 drug arrests in 18 months, the majority of the arrested black. The next two presidents, Gerald Ford and Jimmy Carter, responded with programs that were essentially a continuation of their predecessors. Shortly after Ronald Reagan became
