federal data, blacks were almost four times more likely than whites in 2010 to be arrested for possessing marijuana, regardless of the fact that blacks and whites use the drug at similar rates. Despite a recent Pew Research Poll showing majority support for legalization, the U.S. continues to spend billions ($3.6 billion in 2010) enforcing marijuana laws and, in so doing, practicing racial bias:
...Drawn from police records from all 50 states and the District of Columbia, the report is the most comprehensive review of marijuana arrests by race and by county and is part of a report being released this week by the American Civil Liberties Union. Much of the data was also independently reviewed for The New York Times by researchers at Stanford University.
“We found that in virtually every county in the country, police have wasted taxpayer money enforcing marijuana laws in a racially biased manner,” said Ezekiel Edwards, the director of the A.C.L.U.’s Criminal Law Reform Project and the lead author of the report.
...Researchers said the growing racial disparities in marijuana arrests were especially striking because they were so consistent even across counties with large or small minority populations.
The A.C.L.U. report said that one possible reason that the racial disparity in arrests remained despite shifting state policies toward the drug is that police practices are slow to change. Federal programs like the Edward Byrne Justice Assistance Grant Program continue to provide incentives for racial profiling, the report said, by including arrest numbers in its performance measures when distributing hundreds of millions of dollars to local law enforcement each year.
Phillip Atiba Goff, a psychology professor at the University of California, Los Angeles, said that police departments, partly driven by a desire to increase their drug arrest statistics, can concentrate on minority or poorer neighborhoods to meet numerical goals, focusing on low-level offenses that are easier, quicker and cheaper than investigating serious felony crimes.
