As it’s a “spy agency” we’ll probably never know where they got the genetic database, if they’re not merely bluffing. All we’ll have is the story they wish to tell and whatever snippets they release – chosen to support whatever political objectives have been decided behind the scenes.
Most likely they just secretly bought a copy from Peter Daszak of New York Ecohealth Alliance, who commissioned and funded the research at WIV and therefore hold the ownership rights to it.
Secrecy kills. Transparency now!
