The Cincinnati Enquirer reports on a study of Queen City police which found that cops are more polite to whites than blacks after traffic stops:
Cincinnati police officers walking away from a traffic stop of a white motorist are more likely to end on a courteous note, saying, "Have a nice day," or "Take care."
To black drivers, they're more likely to say, "You're getting off easy," or "The ticket could have been for twice this amount."
The good news?
Overall, the report found no statistical evidence of systematic racial bias by Cincinnati police and concluded that—when comparing similar neighborhoods and circumstances—black and white drivers were treated similarly.
