if you were a particularly sinister CCP official, might you consider releasing a virus on purpose to quell the riots in HK? i have no evidence for this but from a cui bono perspective, it would be a diabolically efficient plan with some plausible deniability.
The fact is that the virus originated in a bat in a wet market. Bats are known carriers of coronavirus in China.
The virus originated in Wuhan. Residents of Wuhan have to cross a controlled border to enter Hong Kong. Hong Kong has 2 orders of magnitude less infections than Hubei province.
Biological weapons are typically highly deadly and not transmissible between humans. You want to be able to target specific populations with a biological weapon. The virus isn't affecting young protestors in Hong Kong, it is mainly affecting people with already compromised immune systems throughout central China.
I hope that we can take the unreasonable accusations of conspiracy by the CCP as an opportunity to examine our own biases and preconceptions regarding China. The CCP is often incentivized to misinform and censor. We have seen this at the regional level with the Hubei governments slow response to this outbreak. I can find no indication, nor think of any reason why, the CCP is not working diligently with international cooperation to contain this virus.
