'Prosecutors are more likely to charge people of color with crimes that carry heavier sentences than whites. Federal prosecutors, for example, are twice as likely to charge African Americans with offenses that carry a mandatory minimum sentence than similarly situated whites.
Drug-free school zone laws mandate sentencing enhancements for people caught selling drugs in designated school zones. The expansive geographic range of these zones coupled with high urban density has disproportionately affected residents of urban areas, and particularly those in high-poverty areas – who are largely people of color.40 Legislators in New Jersey scaled back their state law after a study found that 96% of persons subject to these enhancements were African American or Latino.
Nationwide surveys also reveal disparities in the outcomes of police stops. Once pulled over, black and Hispanic drivers were three times as likely as whites to be searched (6% and 7% versus 2%) and blacks were twice as likely as whites to be arrested.23 These patterns hold even though police officers generally have a lower “contraband hit rate” when they search black versus white drivers.
...the ACLU found that blacks were 3.7 times more likely to be arrested for marijuana possession than whites in 2010, even though their rate of marijuana usage was comparable.
