I'll throw my 2 cents in here. I have zero proof other than my gut feeling that this is a bioweapon. I do have 40 year of biodefense research experience behind me and worked at Fort Detrich on bacterial vaccines where I developed my own aerosol infection routes and developed multi-species models of pathogenesis to establish correlates of immunity. Because I was a one-stop shop doing everything including animal care, aerosol exposures, sample analysis, necropsy, and histopathology, etc. plus I had research programs in endemic areas studying the immunopathological response in human populations to establish immune correlates of protection for candidate vaccines all for the Biological Defense Research Program (BDRP).
I recall the early years when the Department of Homeland Security was stood up and they got the lion's share of poorly performing ciivil servants un-fireable under the then OPMA policies. I was brought in as a technical expert as we were in dire straits for funding so I (and others) was lent out as a research prostitute. This is a little known problem with civil service employees. They are impossible to eliminate and generally rise to levels where they can cause the most damage. However, an opportunity arose whereby agencies in the Federal government had to contribute bodies to the new Department of Homeland Security (as no new vacancies were created when the agency was stood up meaning everyone had to sacrifice personnel) so most, if not all, employees sent to DHS were the worst of the worst. However, the DHS labs (specifically NBACC) also tied into some nefarious microbiologists working at the CIA (ostensibly part of DHS) and it is an understatement to say that what I saw being proposed horrified me.
