bio weapon suggesting this was somehow intentional on the part of china or scientists, or something, in creating this pathogen. that was wrong, and in fact, all the intelligence agencies, including fbi and energy department have said they do not believe there was intention behind it. i think that's part of the problem that the lab leak, we are saying it could be an accidental lab leak versus animal spillover. i also think part of the issue is, of course, china has been totally wrong in not allowing independent investigations, but to this point, i really don't see what level of evidence will have to be produced in order to convince both sides of this that they are wrong. i don't know if we will ever come to a definitive answer, because people are so doug in and how they think about the origin of covid . so what i'm proposing, i just wrote a "washington post" column about this, we can think both are possible grade don't stop investigating, move forward. we need to prevent the next pandemic.
