This is a good debate involving Knut Wittkowski (who has been cited previously on this blog) about whether the lockdowns worked. Short answer: no, because the number of infections in the US peaked on March 8th, before the lockdowns began. You can’t “flatten the curve” if the curve has already peaked! Weird to think that all those stay-at-home orders, business closures and sweeping suspensions of civil liberties were completely pointless. Oh well.
