It's a fascinating proposition.
Do the crimes have to be actually against some sort of law? Are we limiting this to our local laws, any law anywhere, or just the laws of the country we are in? Are we counting misdemeanor crimes or all felonies? What about things that are morally ambiguous, like men wearing hats indoors? Or other things that should be crimes IE: talking in the theater? What about crimes they barely bother to prosecute?
