I don't need to. Just like the law doesn't need to prove innocence. I'm not demanding that you prove anything! Two deadly pandemics started in China in 18 years! Funny how only China has the ability to do that! Well okay then - so you're happy with the continued sale of deadly bats anywhere around the world. This position is actually acceptable if you are against never allowing any travel from these countries ever again without basically having special dedicated isolation hotels at certain airports where people must remain for 14 days before they can leave the airport. Actually this might have to happen before the international investigation is completed, before any recommendations are made by the WHO to prevent this from happening again - presumably the travel bans can't remain in place forever - it's certainly inconceivable. Well I'm asking YOU! You're the one who made the point about the scientist pointing at the US. Again, which part of that are you referring to which points at the UNITED STATES? Here it is again: "A 2018 study of tissue slides and medical reports led by evolutionary biology professor Michael Worobey found evidence against the disease originating from Kansas, as those cases were milder and had fewer deaths compared to the infections in New York City in the same time period. The study did find evidence through phylogenetic analyses that the virus likely had a North American origin, though it was not conclusive. In addition, the haemagglutinin glycoproteins of the virus suggest that it originated long before 1918, and other studies suggest that the reassortment of the H1N1 virus likely occurred in or around 1915." Other than the accounts of Wuhan doctors at the very CENTER of this thing, who are risked their freedom, possibly their LIVES by speaking out! You're assuming that the "app from one doctor to other doctors" is the point at which the Chinese government became aware of anything.
