> I don't think that's true at all. People say that crime increased in San Francisco because of the more progressive DA, but ignore that crime increased less in San Francisco than nationwide.

Well, yeah ... if shoplifting isn't reported as a crime, then it doesn't matter how high the shoplifting rate goes, then official crime rate will still be low.

TLDR: If shoplifting is unreported, then reported levels of shoplifting will be zero.
