IIRC about that article the material that was hidden was not connected to the case at hand. It was just one case wasn't it? Did it change the outcome?
not just one case, and several defense lawyer teams for proud boys have been trying to follow up on it. considering it involves perjury and evidence tampering and that the proud boys are all alleged to have been involved in the conspiracy with each other, one would expect they'd all have a right to see what exactly the fbi hasn't disclosed about them yet.
in functional courts, that is.
there are also allegations of fbi having a "confidential informant" of some kind that continued to be one after being named a witness for the defense, in essence spying on the defense team. those are only allegations at this point, but along with the evidence tampering above, this would also be grounds for a *lot* more information demanded and/or insta-mistrial.
there's a heck of a lot more smoke wrt fbi involvement with proud boys than the shaman's case. the defendants have a right to know exactly how much, and what information they have. "confidential" isn't valid now. if has even the slightest relevance to 1/6 involvement, an honest court will compel the fbi to provide it.
i don't have much faith in that happening.
