I suspect one of the reasons for the feeble response to this whole debacle is that there is almost no measurable damage from illicit FISA surveillance. Id be surprised if there is a single person anywhere in the U.S. who has been prosecuted n the basis of information obtained through a FISA warrant. With all of the advanced technology out there today, I think a FISA warrant does nothing more than provide legal window dressing for intrusive surveillance that our intelligence agencies conducts routinely on all forms of electronic communication.
I think Carter Page and General Flynn may disagree with you.
