As soon as anything is filed alleging any misconduct involving any three letter agency (especially so under the earth-shaking and institution-destroying dimensions that you are going to assert) be fully prepared and expect them to run to the Court, to seek to have all your evidence sealed, redacted, and otherwise pulled from public view.
Sealed and court-redacted, under the usual fiction of "national security interests".
This is their classic cover-up tool, and you have probably seen it first hand in the past.
They will do this to keep from public view the existence and scope of their bad conduct. It will all be concealed and obscured if they get their way.
And then the media will recast it as something else to escalate the propaganda war.
Judges are unsophisticated in this area, and routinely roll over to these agencies on these requests. You must overcome this judicial presumption.
You must have the President directly and publicly intervene to override any agency national security interest claim.
And you must fight like hell to keep the assigned Judge from buying the agency contention. If what you are contending is true, the agency is a criminal actor, seeking to cover up evidence of their crimes. That should be the angle. Appeal the summary evidentiary ruling (as hard as that is), if need be. Do not accept this cover up tactic.
Otherwise, the public will never see the evidence you are claiming. They will bury it under seal and redactions.

Judges have seen it all, from lying ex-spouses, to lying criminals to lying FBI agents.
OP sound like one of those people that kept saying "Nothing is HAPPENING!!!!!" at the FISA court.
There will need to be an evidentiary showing, and it must be compelling and simple. Like this:

It must be this simple.
