So whether you believe it or not depends entirely on you're prejudices. I'm prejudiced not to but others may feed differently.
And it makes absolutely no difference at all. You still need a vaccine, you still need lockdowns and quarantines and to manage your healthcare. And we should all be taking action on China whether it's incompetence (around food hygiene) or incompetence (around bio hazard management).
This is why I hate the whole Lab Leak thing. It's people "straining out a knat and swallowing a camel". It's a distraction and it unnecessarily complicates messaging and discussion that can be pretty vital.
