..but it's not a "common sense conclusion".What I find so strange is that when a lab experimenting on coronaviruses finds itself at the center of a new coronavirus outbreak, people would rather believe the same governments who both tried to cover up and lie about it, rather than what appears to be a more common sense conclusion.
It is not based on evidence .. it's no more than an assumption.
There are plenty of other explanations, so I have no reason to believe it.
