I'm not sure what the Department of Energy's qualifications are (I know they're in charges of nukes so maybe also bioweapons?) but I don't see what relevance the FBI's opinion has.
The National Labs, where a tremendous amount of infectious disease work is done for national-scale questions. I've worked with them in the past, and considered taking a job with them - of the various agencies, they're the ones who have weighed in with probably the most expertise.
