>In August 2013, a report by Reuters revealed that the Special Operations Division (SOD) of the U.S. Drug Enforcement Administration advises DEA agents to practice parallel construction when creating criminal cases against Americans that are based on NSA warrantless surveillance. The use of illegally obtained evidence is generally inadmissible under the fruit of the poisonous tree doctrine.
I'm not saying Trump and his people are innocent or that there's no Russian involvement, I just think it's highly unlikely that the set of evidence that we will see in these cases was obtained or produced with the publicized methods.
Not without a warrant.

Then the defense can present the evidence.
As far as I understand the justice system (which, luckily, is not very well), the prosecution is not out to prove your innocence. It goes contrary to all their incentives, both the police and the actual prosecutor. All advice I've ever heard defense lawyers give on this topic points in the same direction: don't count on police or the prosecutor to seek the truth.
I may be wrong, of course. Thankfully, I haven't had the pleasure of finding this out for myself.
This is doable, I think. It's kind of the case now, and all it would take is a momentary parliamentary majority to enshrine it. But, it's honestly hard to see a consistent legal/theoretical justification for it, if all the data is sitting on a government server.
Are you saying that a court/prosecutor should not be able to demand someone's emails? What if they could be used to exonerate?
Somehow, I just think that once these datasets exist (they do) we will eventually get used to them.
