Thank you for your comment. It's true the WIV does risky research under BSL2 conditions. But for that to lead to a lab leak of Covid-19, they must have a backbone virus, which is unlikely. The WIV disclosed their collected coronaviruses in a paper submitted to a Nature journal before the pandemic, and none could serve as a backbone to Covid-19.

Even in the infamous DEFUSE grant, the researchers proposed working with SARS1-related viruses, not the previously unknown SARS2. (SARS1 and SARS2 are highly distinct btw.) In short, the WIV simply doesn't have a starting virus that could have created SARS2/Covid-19.
