It is convincing. But, what could have happened is that they "found" it locally, and were playing playing with it when it got away from them. It just has some great qualities that are desirable in a bio-weapon. And, it's definitely from Wuhan's neighborhood.

They could have stolen it....did it themselves..or had that harvard guy help them
They knew it could be done after Chapel hill.
There is something about the bat not being local but cant remember story
