Riverfront Times reports on "police patterns in enforcing drug laws, particularly in African-American neighborhoods." The story includes maps showing the ethnicity of the neighborhoods by using US Census data. The reporter discovers that "police in St. Louis County routinely serve high-risk drug raids in black neighborhoods, but rarely in white ones." Another finding is that very few of the targets end up with criminal charges against them, which challenges the efficacy of the raids. The Times also sheds light on three killings of unarmed people by police.
