So LA was being a bit dumb.

I agree with you that some protocols were dumb. Schools should have opened windows, or added UV-C lights, or replaced high-traffic surfaces like doorknobs in large common areas with antiviral materiel, added foot-use mechanisms for opening doors, and so on. Or, if it was too expensive for any of that, asked cleaning staff to spend more time on high-transmission areas like bathroom faucets and doorknobs even if it meant less time elsewhere. But I think there's something more than just outdoor vs indoor going on.
