Well, no one knowledgeable about the field. I have, unfortunately, heard otherwise intelligent people saying that the Chinese government doesn't mind sacrificing it's own people, and did launch it in its own city on purpose (which is, to be clear, ridiculous). "Never ascribe to conspiracy, what is adequately explained by incompetence". I think the evidence is pretty clear that at least the Chinese government believes that the covid-19 virus came from their lab (they could, of course, be mistaken about that).
