> There's literally no way to know what would have happened if no lock down happened. Actually, we do have data. The SF Bay Area has very close ties to China, and corona likely arrived here via air travel in mid-Dec. So anybody who actually wants to make the effort can compare before and after lockdown effects. Also, it's common in large organizations for one dept. to not communicate to another dept. in a meaningful way, so relying on epidemiologists alone for analysis is not wise. There has to be daily, open conversation with local govt. and economists.
