Why can’t the judges on the FISA panel be held responsible for committing illegal activity?
Not only them but their overseer Traitor Roberts.
He is where the buck stops in the Judiciary and he is DIRECTLY responsible for them.
Those judges cannot independently investigate every claim and justification in the DOJ's FISA applications. It is the one legal process where, due to its inherent need for secrecy, the DOJ must present both incriminating and exculpatory information and identify the sources and reliability. The FISA court relies on FBI/DOJ for the integrity of the application and a fair representation of the pros and cons. When the DOJ subverts that integrity, the FISA judges have no way of knowing and only FBI/DOJ can be held responsible for the illegal activity.
Similarly, SCOTUS Chief John Roberts doesn't have time and resources to review each FISA case and isn't expected to; he just appoints the FISA judges on a rotating basis. The problem here is that there is no way to appeal a FISA Court judgement to the SCOTUS because typically the targets of FISA warrants don't and shouldn't know that they are being surveilled.
It appears key information was withheld from the FISA court and they didn't get the entire Steele dossier. I read somewhere that the most ridiculous parts, like peeing in a Moscow bed, were withheld.
That said, had I been a judge on that court and asked for a warrant to wiretap a major party Presidential campaign, I would have given the DOJ people a thorough grilling and demanded their entire file. This wasn't an application for a warrant to search some drug dealers house; this was a big deal.
According to Joe DiGenova , the FISA Court Judges are working with DOJ.
The Judges already know who lied to them and have provided this info to the IG
