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.
Sounds reasonable..
Are you in the legal field?
yes but the fisa court has done nothing since they found out they were duped..
