I think it's probably fair that when this is all presumably past, we'll conclude that some of the measures that we took and that many feel very strongly about weren't super-effective. (And a lot of it boils down to dumb luck.) On the other hand, there have been mitigating measures to some degree in most places so I can't seriously argue that we should have just have said "screw it. Let's just pretend that everything's normal." and act accordingly.
