I think it also depends on your definition of crime or the type of crime that is being committed as outside of the scope of truly violent crimes or crime where there is a clear victim there are a lot of crimes that really should not be a crime in the first place (like possession of certain plants) and there may be many instances of truly victimless crimes that would go "uncaught" and thus untracked if an authority figure was not observing them.
