As the artical author notes,
"posed some challenges for the controversial anatomist"
Gunther von Hagens, has a habit of self publicity big style... Including an autopsy "live on televison" in the UK (Channel 4) back in 02.
He usualy wears a black hat and as was remarked by a journo at the time, he just looks like he's used plastination on himself.
Also this bit from the article sent bells of in my mind,
"to a plastination facility in Dalian, China, to be preserved by anatomist Gunther von Hagens"
China has a long history of "human rights" issues with regards prisoners.
Stories abound about "organs for sale" supposadly from prisoners.
Back in 2006 representation was made to the UN (by former Canadian secretary of State for Asia and the Pacific, David Kilgour, and vice-president of the European parliament, Edward McMillan-Scott) that China was "Organ Harvesting" prisoners,
Edward McMillan-Scott is a UK politician, He resigned from David Cameron's Conservative party a few days ago over Conservative party machianations in Europe (he is now a Lib Dem). Which is why the "China Organ Harvest" issue was in the news again. I have no reason to doubt that he believes China has and probably still is carrying out organ harvests of prisoners.
