Most "N95" masks that are generally available (i.e. those from Home Depot) have the rubber flapper valves for exhalation. Think they do anything much useful medically?

How many people have you seen wearing clear plastic face shields or bandannas tied around their face like Ol' West banditos, with the bottom open? How about with the mask pulled down below their nose? (Disclaimer: I did that the other day; I was at the optometrist and my breath was fogging up the lens thingy.)

The early pandemic mask messaging was wrong. A postmortem might very well find that they made the best recommendations they could based on what they knew.[1] Unless you've already decided that they screwed up because they're lying idiots.

Based on what they knew, or what they should have known? I never said they were idiots, but Asian countries already had data on mask use during SARS. I also don't think they were lying about what they thought at the time, moreso they were misleading about their level of uncertainty on the topic. If they really did think masks were useless with high probability then I think they missed some preexisting literature.
