I don't think anyone except extreme # people would believe that the Wuhan virus lab _intentionally_ released # or that it was a germ warfare candidate, but an accidental release (e.g., contaminated employee visits the Wuhan seafood market, coughs, passes virus to dozens of people) is a reasonable possibility, as is people catching it from a live animal's sneeze at the market.

I don't think there will ever be proof either way, but the rapidity and stringency of their response _once they finally acknowledged the outbreak_ and their quickly producing genetic maps could be used to argue for the lab's early involvement. (Personally, I'm neutral on either direct-from-animal in the market or direct-from-animal in the virus research lab.)
