TG-
The case against Bruce Solie is entirely based circumstantial evidence, and even there we hardly have a complete record.
There are no wiretaps, no confessions, no confirmed meetings between Solie and KGB'ers, etc. No records of financial inducement, or that Solie was blackmailed for being a homosexual, etc.
Solie was never put on trial, and is too dead now to mount a defense, or provide explanations or an alternative narrative.
Nor has anyone in the KGB ever said, "Yeah, Solie was one of ours."
You have CT against Solie, as does Newman.
I lean towards Solie being a KGB asset, but I recognize what I have is a suspicion, a CT, not a fact.
