By “developing” are you insinuating they created or modified the virus? We don’t have the wherewithal to “create” something like that. I believe they were studying the virus...I don’t want to speculate for a biological weapon...regardless....it infected people who worked in the lab who unknowingly spread it outside the lab due to the symptom-free incubation period. Shit got out of hand. China tried to cover it up, couldn’t contain it and boom....here the hell we are.
