Chief spokesman Anthony Guglielmi said the department’s Bureau of Internal Affairs found that the two Wentworth District officers acted properly because they had probable cause to make the stop.
Officers at roll call had been told to be on the lookout for high-end vehicles because of a rash of thefts throughout the South Side.
The officers stopped Rush in his Lexus after learning from a police dispatcher that its license plate was registered to a different vehicle.
The video shows that throughout the stop, the officer and Rush spoke to each other in calm tones.
However, at about six minutes into the video, Rush challenges the validity of the stop.
