What I would ask about these "power law" situations: Do we have any idea what moves someone from bad cop to really bad cop or homeless to homeless-and-totally-down-and-out?

While only a small number reach the "really bad" level, it seems plausible that there's a larger population who could move into that level if the competition or bad examples or whatever other restraining factors were removed?

Sure, only a tiny minority is flagrantly offending at a given point but if one doesn't understand how this minority arises, one doesn't really understand the situation.
