Just read http://www.huffingtonpost.com/2012/05/11/chicago-police-misconduct_n_1503355.html , an account of how Chicago's losing tens of millions of dollars due to the actions of "repeat offender" abusive police officers.
I think it's no secret that the CPD (including Internal Investigations and the Review Board) shelters abusive cops and doesn't do nearly enough to get them out of the force.
I think it's also disturbing that these bad officers are not outed sooner: Their co-workers and bosses must know at least a little bit about what's been going on: Why aren't the bad cops reported? Are the remaining supposed good cops just accomplices in hiding this criminality within the force? Or do they not have an option for reporting this stuff? (e.g. they won't be promoted/ they won't receive protection from fellow officers in dangerous situations)
It's too bad that CPD seems to be more loyal to its own than the public it is supposed to serve. Chicago is a world-class city. We should have a world-class, professional police force, not a haven for abusive goons.
