Whatever is going on in China, I don't think it's coronavirus anymore. Not to say there may not be a lot of pneumonia cases, but I think the lockdown is cover for other things.
That is what I think, too.
If you want an effective way to implement a bio-warfare program, you would not simply release the pathogen. You would create the appearance of an outbreak or an epidemic and you would create a vaccine that would be the real bio-warfare agent.
