This man is the closest we'll ever see to a "Manchurian Candidate." Or, in this case, a Manchurian public official.
He is owned, lock, stock and barrel, by the PRC.
He's not out for the money-though that probably helped to grease the skids-but for the power. He is essentially a tool of Hu Jintao and the corrupt gerontocracy that runs the emerging "Red Dragon" of the Asia-Pacific region.
Like the communist tools who facilitated the easy transfer of power from former European occupiers on Macao and Hong Kong to their new colonial masters, the Chinese government, Berger and people of his ilk are simply paid stooges of Mao's little red soldiers.
I do believe that scenario has legs.
