I was like no way can anyone determine that without examination and sure enough.

From the letter

>>We want to emphasize that we do not know if the emails, provided to the New York Post by President Trump’s personal attorney Rudy Giuliani, are genuine or not and that we do not have evidence of Russian involvement -- just that our experience makes us deeply suspicious that the
Russian government played a significant role in this case.
If we are right, this is Russia trying to influence how Americans vote in this election, and we believe strongly that Americans need to be aware of this. >>

So basically they don't care if they are real they are real or not, they will just Blame Russia anyway. because it is their MO.
Great intelligence work for a basket full of sherlocks.
God Help us, these people have no credibility and that is a bigger threat than Russia. .
