"Among the nation's largest cities, Chicago stands out for both its high murder rate and for the number of its murders that go unsolved. In recent years the police have been solving about 4 of every 10 murders in the city, but police data show the rate is even worse when the victim is African American."

I'm not sure what the effect of that observation is, though - key and immobilizer security is extremely important still, because cars which are stolen by any mechanism (tow, stolen key, transponder relay, etc) then need to be resold or broken down for parts. Especially in Europe where control module security is generally both more robust and more insurance regulated, many parts on a stolen vehicle are increasingly not valuable unless the immobilizer / key enrollment system can be bypassed.
