In theory, if crimes exceed prosecutions, then number of convictions being closest to the number of prosecutions should indicate an effective use of resources. The real problem is that thorough investigations are rare for most crimes and it's just and industrial-scale process to show the elements of an offense were met by a preponderance of the evidence.

And for far too many people, harsh punishments inflicted on expendable whipping boys are an all-too-satisfying way of doing that.
