Of course it's just a coincidence that a few of the agencies have now said the lab leak theory is a possibilty just as the US is turning up the heat against China. What better propaganda tool than being able to blame them for Covid?
Whatever the truth of it, the timing of this change (and remember this is only three/four (?) agencies that are saying lab leak is possible) is so transparent.
The FBI is one of them which is ok but one of the others is the Department of Energy which is involved in a lot of biological research but they probably don't have access to as much intel as the actual intelligence agencies that are still not on the lab leak cause.
Also, rarely mentioned in these things, all the agencies that are coming out for lab leak are doing so with "low confidence" which is spook speak for "meh, it could be, who knows?"
