It does seem odd that the FBI has claimed in legal filings not to have taken the DNC computers into its possession for forensic analysis, relying entirely on 3rd party analysis, though. I believe this info can be sourced from filings in the Flynn case, which I really wish someone would put up a full archive of, it's been pretty crazy.
The dossier was oppo research. There’s literally nothing controversial about any of it, other than it was leaked and its target successfully spun the few disputed claims into evidence of mass political conspiracy.
When you get basic facts like this wrong, it makes me wonder what your interest really is.
