Chris Martenson, "Are Our Scientists Lying to Us?", Peak Prosperity YouTube channel (04 May 2020)
How long this link will work I don't know. As we know, videos are getting taken down thick and fast these days if they don't toe the official line on the pandemic—and Dr Martenson has had his Wikipedia page deleted for being a naughty boy—so we'll see what happens. Anyway, I think this is a "must watch" video, and possibly very important. Contrary to confident official statements that SARS-CoV-2 is best explained as the result of entirely natural mutations, Martenson points to evidence that part of its RNA sequence ("specifically the polybasic furin cleavage site PRRA") "has all the appearance of an "insert" (i.e., something that does NOT look like a natural mutation)."
