It's been debunked so many times now he should really know it. The most basic common sense should tell you, even if you believed that they slipped up the first time this reared its head (Kirk shooting), that they wouldn't keep making that same mistake and googling their false-flag assassin's name so any tom, dick or podcaster could get the details with a couple of clicks. That's without reading any of the refutations. The twitter image he included of the "trends" came out almost immediately and was debunked about two seconds afterwards. In this case the whopping 16 hour time difference between the Oz and the apartheid state can play a massive part.

Other than that, even with no evidence I'm suspicious of these things but this google trends crap has to die.
