Today's edition of Brad Delong's ongoing commentaries on Alan Greenspan's recent book are making it clear that Greenspan has damaged his reputation even further by not just shutting up and going away.
[Alan Greenspan's] complaisance at fraud ... is the reason why history will judge that he was profoundly unsuited to head a central bank ... and that his reputation is today in shreds.
...His lack of concern with fraud in the 2000s has to be classified now as an economic-more-than-felony.
...Greenspan's Randite roots have led him astray: for Greenspan, there is moral value in not protecting people from the consequences of their actions--and "consequences of their actions" appears, for Greenspan, to include falling victim to fraud.
More good stuff in the comments.
