I'm wary of posting before watching the videos ("and so you should be," I hear you chorus), so I admit to not knowing whether this hunt is put in context, but the decline of the tiger was, to put it mildly, hardly a secret, even in 1967, so they had better have had a good excuse for contributing to it. Maybe they did, but if so, I think it should have been made clear by the OP from the start.
