The example I had in mind was Goldman and AIG. AIG had lost effective internal controls when the former CEO departed and insured below reasonable cost. I do not know if buying a CDO makes sense to free up capital if the CDO is properly priced. I will bet that lots of CDO issuers on Greek debt would be happy to give back  premium they have received and then some to be off the hook on those CDOs. And even good rocket scientists make rockets that explode.
