Do you think we'll ever get to the point where those returning positive tests will be removed from the community (into enforced isolation, not the North Korean version of removed .)? The whole exercise is largely of good faith that people will do the right thing. And it has been proven time and time again over the last 3-4 months that whilst the vast majority of people will do the right thing, there's a small, but not insignificant minority that do not and will never do the right thing, for whatever reason.
