A “cluster” doesn’t mean anything when we are dealing with something that they are telling us is “so contagious” that we have to wear masks or we will infect people 6 feet away from us with just our breath. Contact tracing isn’t guaranteed, it’s a guess, especially when even asymptomatic people can transmit it. And besides, if you think the business owner is responsible for infection because he opened, then the people who showed up “against the recommendations of doctors” are also equally responsible for going out when those same experts told them not to. so either they are contributorily negligent and there is no case, or then we have opened up lawsuits among people, where you can sue a single mom who tests positive but is asymptomatic so she stops at the Walmart pharmacy to pick up her baby’s medicine on her way home. Should make this a fun country to live in.
