Free-range people with questionable/compromised health and immune systems are in particular danger. Exempting homeless camps was insanely lazy and cowardly, IMO. SF is in a particularly bad situation, IMO, because it is so compact and vertical, and the homeless people are literally in the streets and parks. They are in much closer proximity, as well as contact, with normal people than pretty much anywhere else in the Bay Area. Outside of SF, encampments tend to be under freeway overpasses and along creeks. The closest I come to an encampment is probably 20-40 yards, I see a homeless person on the streets very occasionally, still 15 or more feet away. If SF doesn't get their ... you know the metaphor ... their homeless problem may be "solved" by the coronavirus, taking a fair number of ordinary citizens as well.
