Sure, I'm not denying the plausibility of either scenario. But, which one is more likely: a virus jumped from animal to human, just as has happened many times

Sure, I'm not denying the plausibility of either scenario. But, which one is more likely: a virus jumped from animal to human, just as has happened many times before in history (and, without our help, for that matter), or safety procedures were not being followed in a lab that studies viruses with the very highest level of safety controls? How many times has the latter happened compared to the former?
