Dr. Chen spoke concerning human rights in China.  Millions of Chinese people have been arrested and/or tortured for their beliefs or political views.  Some have even had their organs harvested and sold.  In the US it can take years to get an organ, but in China it takes 2 to 4 weeks.  Prisoners have been forced to have their organs harvested by the Chines police, legal and military system, with their families never knowing what truly happened to them.  The human rights movement started in 2004.
