I think it's possible the virus leaked from a lab in China, but it's also possible it was transmitted in the wild a la "wet markets". Either way, regrettably due to Chinese propaganda and tight controls on speech and the press, it is highly unlikely the world will get an open and honest investigation from the Chinese government.

My own idea is a combination of the two. I wonder if it leaked out of the lab by a lab employee trying to make some money on the side by selling lab animals to the wet market. (Note well: This is just my "seems kind of plausible" guess. I have no actual evidence to support it. And no, it's not actually "my own" idea - I heard it suggested by someone, who also had no evidence that I recall.)
Nobody would sell lab animals from a virology lab to markets to eat. The consequences are obvious, animals would be accounted for, the risk would be extremely high to the persons future, and the profits small.
It's the kind of ideas you find on racist conspiracy theory blogs and you shouldn't share it here.
