Oh but all those in management who repeatedly signed four separate FISA warrants are responsible too - the scapegoat will not be sufficient.
I've read the IG report. The top officials whom signed off insinuated they rubber stamped the applications because their staff said everything was on the up and up. Trisha Anderson in the FBI general council office testified something to the effect the FISA was pre-approved by senior DOJ leadership for the first FISA application in Oct 2016.
