As with other attempts at sparking discussions on the origin [1], I'm not a virologist, just a bystander whose curiosity was piqued by the proximity of the sole lab in all of China that's equipped to handle/research extremely infectious viruses and that of the outbreak.

My observations (all facts)

1. Proximity of outbreak to sole advanced virology lab in all of China, suspicious

2. Publications ( https://jvi.asm.org/content/82/4/1899 )from lab suggest they were dealing with CoVid-19 like viruses for a while.

3. State of China would strongly deny/cover-up the lab to be the cause of outbreak, even if that did happen. I'm not suggesting they engineered the virus, just suggesting that they were researching animals with the virus, and a freak case of violating safety protocol let to the virus leaking to the nearby seafood market. Again - attributing this to clumsiness, not malice

Given the above, I think an investigative journalist would find the circumstances fertile enough for a deep investigation. Given how hard it is to identify patient zero of the outbreak, I think journalists need to go down this path of investigation
