This is the second interview with Professor Knut Wittkowski that Martin Armstrong has posted, https://www.armstrongeconomics.com/international-news/disease/professor-knut-wittkowski-update-interview/.
I really like Wittkowski. He comes off as extremely credible, and he states unequivocally and with support that the shelter-in-place was unnecessary, and has made things worse. YouTube will probably ban this soon, but it will be posted by others, so if interested but this link is broken, search for it.
