Hardly surprising that a video full of dangerous misinformation has been pulled. It would be worth reading about this particular professor on Wikipedia, particularly his support for alternative medicine, his false claim to have been a professor at Imperial college, and his claim that the UK's NHS is "the last bastion of communism". https://en.wikipedia.org/wiki/Karol_Sikora
So what is so dangerous about it? Perhaps you need to consult a dictionary as to what danger really is. I don't know these people that made the video and I don't subscribe to magic crystals or whatever they are pushing/saying but I do know what Epidemiologist Neil Ferguson from Imperial college created in his flawed modeling - a world wide panic. That is what has been dangerous. Google is a private company I suppose…
You don't think the tens of thousands of deaths in Italy, Spain, France, and the US had already caused that panic by the time his model was released?
