Good point. Arguing about who or what to point the finger at for SARS-CoV-2 seems more like politics than epidemiology. The evidence of a laboratory source is unclear enough, and the chance of a natural source plausible enough, that I'm not sure how the cost/benefit is supposed to work out here.

Not to mention if your goal is just to point out the ethical lapses of the Chinese government, you don't really need any extra ammunition.
