Over the past ten years, the population of Dismaston has grown five times as large as it was. During this time, the average income in the city has risen substantially, and a tremendous amount of capital has flowed into city. An independent audit found that, somewhat surprisingly, the number of violent felonies reported per year is now lower than it was ten years ago.

Each of the following statements below, if true, would explain the somewhat surprising finding EXCEPT:

A:White collar crimes, which are almost always non-violent, tend to replace street-crimes during times of prosperity.

B:The police now have a computerized filing system, so that it is almost impossible for a violent crime to be unrecorded.

C:During this time, the state considerably lengthened felony convicts' waiting period for parole.

D:The police force has expanded in number and is equipped with the latest crime detection technology.

E:The city is now much better lit at night, and security cameras protect a large number of public venues.
