"Our analyses clearly show that SARS-CoV-2 is not a laboratory construct."
But that's not the point! This is a straw man argument. The main concern and possibility is not that this virus was constructed in a lab, it's that it was released from a lab.
None of these headlines denying Chinese lab responsibility unequivocally state that the virus did not escape from the lab in it's natural, unadulterated state; nor do they state with absolute assurance that an adapted virus didn't escape. All they say is this -- that the virus was not contructed in a lab, meaning, in it's purest form, that the DNA was not constructed form scratch in a lab.
It's faulty logic. It's an old political trick. It's like Bill Clinton saying, "I did not have sex with that woman." No, he didn't have intercourse. He just got a blowjob. And unfortunately for him, she didn't swallow. These scientists are making sure they swallow.
EDIT: If you're unfamiliar with the Clinton case, he was busted because his semen was found on Lewinsky's dress.
