It makes all the difference. If we had known in January 2020, the virus could have been stopped so easily. The likely bioweapon could have been left in China — just by stopping the flights and instigating a two week rigid quarantine.
Think about the effect it would have had in January 2020 if people thought Covid was a man-made experiment. The public would have clamored to stop the planes. Borders would have gone up overnight. There would have been much less of the fatalistic acceptance that it was just another inevitable pandemic "like the flu" that people had to deal with. The suppression of the "lab leak" theory served the CCP and Anthony Fauci and co. It also served Tedros Adhanom, the head of the WHO who told the world to keep the border open on February 2. But so far that suppression has cost nearly five million lives, plus the mayhem, economic damage, long illnesses and debility.
Last night Sky News aired the documentary What Really Happened in Wuhan by Sharri Markson. We find out more about who knew what when, but not quite enough.
