Wow! This is a huge and detailed effort to investigate the hypothesis that Chinese labs were the source of the pandemic. I agree that a maximal effort to find the source should be undertaken.

In that regards, have you considered similarly investigating the Chinese claims that it was US labs that were the source, say Fort Detrick? Any cover-ups there? Historically, hasn’t the US tested pathogens and lethal radiation on its own citizens and covered it up decades before they were revealed?

Since the world views China as more trustworthy (see https://www.washingtonpost.com/world/2019/02/11/why-much-world-now-feels-more-threatened-by-us-than-by-china-or-russia/), shouldn’t some similar investigation on the US labs be done? Is the US government so truthful and transparent? Do US presidents lie? What keeps you from even a cursory investigation of the Chinese claims? At least investigate in order to thoroughly debunk.
