[RV86]

I wanted to add -- the two most compelling pieces of information I've seen that make the lab accident theory more plausible to me are: 1) The verified existence of the bat-originating corona virus that killed 3 miners with Pneumonia some years ago being housed/researched in the WIV 2) David Baltimore of Cal Tech's remark ""When I first saw the furin cleavage site in the viral sequence, with its arginine codons, I said to my wife it was the smoking gun for the origin of the virus. These features make a powerful challenge to the idea of a natural origin for SARS2"

But then again other people have explained the furin cleavage site exists in other beta coronaviruses - so making a definitive "smoking gun" statement without further research seems premature.
