(Decanter) - Robert Parker has called Pancho Campo a 'lightning rod' for controversy as he announced a 'totally transparent' legal investigation into the series of accusations of cash for tasting that have dominated the wine headlines for the past weeks. Parker, publisher of the Wine Advocate, said he ‘remains appalled’ by the ‘lynch mob rush to judgment’ of bloggers, including award-winning Decanter writer Jim Budd on his blog Jim’s Loire.
