If you look at lower level crime (theft etc.) Western Europe and especially the Nordic countries are not doing that well. Sweden for instance has the highest levels of theft and burglary in the whole Europe by quite a margin. Not saying "too nice" prisons are too blame for this, there are certainly some more important factors (hint: recent immigration and failure to integrate second/third generation "immigrants" (couldn't find a better word to describe this group)).
