Moving here so as not to further clutter the other thread -- I see what you're talking about now -- you're referring to a PDF document they've got linked, not the website itself, so that was my confusion.
However, I think you're misinterpreting what that is saying. They're not saying that 95% of all crime (ie. all non-violent crime) shouldn't be enforced, you're inferring that incorrectly from the 5% statement. The very next sentence makes this clear:
