Although anything is possible, this is no evidence, and I hardly believe it.

People lives are worthing much more than their organs when they are used for labor so I don't see any reasonable benefit from doing that. Plus, Falun Gong has a long history of fighting this, still without any evidences brought to the table, so I have some doubts about their assumptions.

The issue in Xinjiang is already serious enough, no need to add some unconfirmed facts which may just make us lose credibility if they're proved fake.
