Las time I looked it had many levels at +10 Crime/turn. As it also has Pollution with +10/turn. No real scale just 10 levels of +5 or +10. Unless you changed it when you added your Criminal and Law units.
Disease and Pollution used to be dependent upon the

generated in your cities. With the new property system you can't tell if your cities are diseased or polluting by the

faces any more. It's now abstract and you've lost that visual sense of where your at with

or

. Players complain they have too much

in their cities because of this abstraction.
All I know is that we've seemed to have lost something in the translation. The old way just worked better for me. And really pollution was a factor for Disease (

,

) before and not a separate entity. That's why I think it's unnecessary. Same goes for Tourism.
The Mod worked very well with out either in it before and it was less micromanagement "fiddling". Also less xml and other coding to deal with too when trying to keep the mod stable. Over saturation imhpo.
