2008 Illinois Traffic Stops Statistics Study has been released. The Atlantic’s James Warren parses the reactions:
The most significant racial disparity involves consent searches. While the total number of such searches has dropped sharply —by 33 percent—since 2004, they are applied disproportionately: an African-American driver is about three times as likely to be the subject of a search as a Caucasian driver, with a Hispanic driver 2.4 times as likely to be the subject of a search. But when vehicles are searched, whites are more often found to be hiding contraband. Police found contraband 24.37 percent of the time when a white agreed to a search, but just 15.14 percent of the time with a minority driver. This finding is consistent with other studies nationwide.
Some are convinced that this evidence points to a clear pattern of discrimination. As Harvey Grossman, director of the Illinois ACLU asserts, “The five years of data show a pattern of continuing disparate treatment based on race, particularly with consent searches.” In light of this view, when the 2008 report came out, Grossman urged then-Illinois Gov. Rod Blagojevich (remember him?) and Blago’s post-impeachment successor, Gov. Pat Quinn, to ban all consent searches by the Illinois State Police.
Others are less convinced that the data shows bias. Kwame Raoul, who succeeded Obama in the Chicago South Side state senate seat and is a former prosecutor, notes that one explanation for the disparity in consent searches may simply be that “whites are more tuned in to their constitutional rights, so they decline more often.”

Raoul’s assertion doesn’t really bear out in the numbers. Continue reading
