I can't help thinking that if you were a white supremetist with a belief in Eugenics Covid 19 is exactly the sort of thing you might have come up with. A virus which wipes out the elderly and unhealthy and kills more BAME people that caucasian. There was a theory some time ago that this particular virus had escaped from a research lab. Is it possible? The US claims that the virus escaped from a Chinese lab and the Chinese say it was brought over by a US contestant in the Military World games in Oct 2019. It just passes the time investigating them!
