Proper countries put a testing-and-quarantine regime in place and have paid sick leave. Not the US, unfortunately.

What is shaping up to be an absolute catastrophe is the Black Lives Matter demonstrations all over the country. Would you consider talking to a contact tracer after you've been to a protest against the police? People will justifiably think it's one of those test-your-meth stunts that sheriffs at times pull. Well, now there's the blowback.

Yeah, police really should have chosen a better time to murder someone on film and then have authorities ignore it for days. Protesters should go home to avoid spreading disease. They can resume protesting the next time an officer kills someone for the crime of having the wrong skin color. It will surely happen again soon.

Even if you are willing to talk to a contact tracer, what good will it do? The vast majority of a protester's contacts would be from the protest. Under the best of circumstances, that is a black hole for contact tracing.

Imagine someone was at a BLM demonstration, possibly did some light rioting (spraypainting, flyposting, damage to vehicles), and the following morning wakes up with respiratory symptoms and tests positive for coronaplague. Now the contact tracer calls. Anyone would think this is a sheriff's ruse, trying to find out what his circle of friends is.

Not with the Apple/Google solution, because the phones in the crowd should be able to exchange keys with each other. But it hasn't been deployed yet.
