I know, I think they backed off on that statement .
I think its more likely that someone was sloppy at the lab..
I read an article abt 1 month ago (think BBC) that said that they rate the labs from P1-P4, p4 being the top rank. They said that the Wuhan lab was operating at a p2 level with lots of errors etc..but they had P4 viruses there.. It was the Who or the UN that said it, cant remember, will try to find the article
