There's a lot of criticism circulating of the Centers for Disease Control, mainly that they said at first masks were not necessary when COVID-19 came along and then switched and said they were. I don't quite get why this was so horrendous. I just thought, "Okay…so it's turning out to be worse than they first thought." Lots of problems do.
Kevin Drum has a post up which some would probably think makes him an apologist for CDC mistakes but I think he's just trying to explain why they weren't as outrageous as some think.
