I think the reasonable question in the lab breakout case is "was the risk assessment used to determine the Biohazard Safety Level the work in the lab was carried out under sufficient, and do we need to change processes to reduce the risk of such a breakout in future (e.g., by increasing the BSL needed for such work)".
That, to me, is the interesting part of the lab breakout case. Are we regularly underestimating the risk of novel viruses in research laboratories?
