Obama and his people committed great crimes. Judge Collyer facilitated the crimes and should be called to testify to Congress.
I think the FISA court needs a team of 3 constitutional rights lawyers that reviews requests and acts as a defense team for citizens before the court. And that team should be granted authority to independently confirm what’s being presented to the court. That way the court remains secret but there is some form of check and balance and some representation of defendant’s rights other than just the judge.
But the danger with any system like this is that they get too chummy with each other.
