If it can be proven that a KNOWINGLY false dossier was presented to the FISA court which then, under false pretenses, issued a warrant to spy on American citizens (for example Lt.General Flynn), then this is not only a scandal of epic proportions in American History, it makes Watergate look like a minor episode, in comparison.
In spite of that they still lost. The people will not be denied.
My guess is that President Trump has the proof. But when will he drop the hammer?
Watergate X 100,,, true, but it wont be prosecuted until long after Obama and Hillary ran the last election....
This is epic, but it has a long swim against the current of a swamp long since polluted by swamp creatures attempting to corrupt the process of justice...
I would think following that would be any thing found under a false warrent is not admissable in court and any findings of a court would be void. Hence, Flynn would have his conviction reversed and record wipped clean. And then he would be in a position to sue the crap out of the DOJ and FBI to recover all his lost wages, lawyer fees and a wopping big number on the damage to his reputaion, to boot.
