I wouldn't say that all GOF research is for bioweapons, part of it is to see where the virus is likely to evolve next and protect against that, which is more on the defensive side of that.

Doesn't mean it's less risky, mind you, and this is convincing me that the experts on this need to reassess whether it's worth the risks and if so, what safety precautions are needed. I would think that BSL-2 is just way too low, but I would defer to the scientists on this and only say that I think this shows that anything done to make something more infectious to humans should be treated as though it already was highly infectious to humans.
