At a practical level I don’t think there’s much difference between the lab link being a 7% chance vs a 70% chance. What’s more concerning is the potential of future leaks and what responses they might result in. The possibility that local officials get in CYA mode over a possible lab leak of a more dangerous virus is seriously concerning.
None that I've seen.
And the possibility of a future leak is probably unrelated to the possibility of this one having been a leak.
Which has little to do with the existence of said evidence. I’ve never seen direct evidence for the year Columbus sailed.
Anyway, many things that would make future leaks less likely also make past leaks less likely. The types of experiments being conducted and the types of labs those experiments are conducted in. Oversight, funding, and systems for reporting safety issues etc etc.
But that is a lie. From the article:
“The Energy Department now joins the Federal Bureau of Investigation in saying the virus likely spread via a mishap at a Chinese laboratory.”
DoE does a lot of civilian stuff now (electrical grid, cybersecurity, etc.) but it's kind of an add-on. The first couple of national labs - places like Los Alamos and Oak Ridge - are historically related to the nuke mission.
