An Illinois study of racial profiling in police stops is set to expire in July. State lawmakers are considering whether to keep collecting data.
The 2004 law, sponsored by then-state Sen. Barack Obama, requires police to keep track of the driver’s race and the outcome of the traffic stop. It was later amended to include pedestrian stops, as well as consent and dog sniff searches.
Each year, about 900 agencies report traffic stop data. It’s then analyzed by the Illinois Department of Transportation to determine whether — and to what extent — race plays a factor in police stops.
