>>We do know why they met, thanks to Trump Jr's emails and his TV interviews saying so.

You've missed the point. Unless you have other emails, Trump JR's email does not admit trying to form a connection to Russian government and nor does a post hoc interview that will be reliably self serving.

>> but you seem to think this is a slam dunk and it is not. Some believe Clinton and the DNC may have violated a ban on foreign contributions to campaigns, though others disagree and emphasize potential disclosure violations by filtering payments through a law firm. interpretation of reporting requirements for subcontractors could be used as defense, and thus that the dossier work was accurately reported as legal services.

I thought so too and had made that same point here long before you- until it was pointed out elsewhere that "indirect" solicitation is also a crime. Read the statute again. And maybe consider its reference to "context."
