Surely that sory of video would be easy to fake if needed these days?

I think being able to produce reliable supply chain traceability is indistinguishable from keeping detailed notes on a criminal conspiracy. None of the players want that besides the consumer. Never happen.

Sure, but it isn't clear to me that China actually cares about stopping rhino poaching, and I imagine the major players in the conspiracy never set foot in South Africa, and just have local low level agents (ie the ones we are told are so poor, they need to poach the rhinos to survive) exposed to consequences.
