Re: Use of proximity-tracking for criminal cases

Everyone keeps missing the 800kg gorilla in the corner - these apps, whatever method they use, *depend on quick, reliable testing of significant numbers of people*. This isn't even close to being available - the tests are slow, they have about 20% false negative and 10% false positive rates, and there aren't enough to test the people at most risk. Worse yet, there are no better tests closer than press releases.
