I'm not all that sure how looking for somebody to blame does anything at all about bringing the damned thing under control!I'd prefer a theory supported by current virologists and not just something by a 78yr old journalist, whose reputation in recent years has been far from spotless. This smells of right wing politics to me, rather than science.
It's certainly possible the virus leaked from the Wuhan lab. After all, they do research on bat viruses there. But I take with a pinch of salt the assertions that it can't have been simply from a natural source. It seems most of the virologists who have worked on it think it had a natural source.
