 Harry Wu, a human rights activist, has questioned the Falun Gong's claims that Falun Gong members are specifically targeted for large-scale organ harvesting.International human rights lawyer David Matas argued Harry Wu's July 2006 article showed his views in his 21 March letter were formed before completing his investigation, so Wu's views were not based on his full investigation.Further, Harry Wu characterized the volume of organ harvesting Annie described as "technically impossible", but it is technically possible, according to medical expert.
