The Champaign City Council explores the idea of body cameras for its police officers at study session Tuesday night. 

After video of a white Chicago police officer shooting a black teenager 16 times was released to the public, Chicago Mayor Rahm Emanuel became the focus of intense backlash. He responded by firing Police Superintendent Garry McCarthy. In many ways this was history repeating in a city that has had twice as many police chiefs than it’s had mayors in the past six decades — and more than its share of police scandals.
