Hey how much a real world example? Six of CJ staffers tested positive for COVID. If they were not tested, they would have worked the rally and spread it to other people. Those six would have turned into dozens, hundreds or more. Instead they quarantine themselves and don't spread it. So, yes testing is important. Isn't it amazing that something so simple, has to be debated.
Just curious how many died people are needed for the deniers to admit this is problem. 500k dead Americans? 1 million? Or does the number not matter as long as it is just old people dying?
