It is just not good to get the Judge mad.
"The DOJ-NatSec Division and FBI reported issues of fraud upon the FISA court in October and November prior to the IG FISA report release. Specifically, the DOJ notified the FISC that OGC Kevin Clinesmith had manipulated and falsified evidence. On December 5th, Judge Coller responded to that series of notifications with an order.
On December 9th, when the IG FISA report was made public, the FISC was given a declassified version of the report and was able to review for the first time. It was from that IG review that Collyer was able to establish the full context of the fraud upon the court. The court was given no advanced notification as to the totality of fraud upon the FISC other than a preliminary ‘head’s up’ on the OGC Clinesmith compromise."
