So you believe a charge regarding Russian Collusion is still coming? Thst was the pretense of this whole investigation. You can't make up a reason to investigate somebody and then use crimes you may find throughout the investigation to justify investigating to begin with.
Now if the opening of the investigation was legit, I'd have no problem with crimes being uncovered in the process of the investigation, even those completely unrelated
You are wrong.
Some of the defendants have already tried to make the argument you are now making. They lost.
First, as a matter of law:
an alleged failure of a prosecutor to establish the charges underlying the initial basis for an investigation is not a basis to conclude that the investigation was invalid. The defendant has to show that the basis was actually fictitious.
Second, you're wrong about what the basis for the investigation was. It wasn't "collusion"; that was a subcategory
The basis for the SCO was, and this is a quote: "to ensure a full and thorough investigation of the Russian Government's efforts to interfere in the 2016 presidential election."
Said interference has already been established and the investigation validated thereby. The investigation of that interference brought a lot of other things to light.
The letter also mentioned subcategories, such as "any links and/or coordination between the Russian Government and individuals associated with the campaign of President Donald Trump."
This is what you're referring to as "collusion", but it's not limited to collusion. It's also on the same level of importance as another subheading of "any other crimes."
It may apply to the initial warrant. It would seem that everything under the sun is being found with the "collusion" warrant that is not collusion.
There was no "initial" "collusion warrant." There was an appointment letter about investigating Russian interference. Warrants and appointment letters are
entirely different things. The fruit of the poisonious tree doctrine is about 4th amendment issues. Not appointments. (Incidentally, the appointment of the SCO has been challenged in court and has been repeatedly upheld).
And Cohen's investigation did not even come out of the "collusion" investigation. This is something that you should know, and is why I asked you who you thought would be helped by the poisonious tree argument.
