Rivero's threads ran the range from believable to really whacky. But most of the subject material was topical, e.g., Ron Brown, John Huang, Vince Foster, etc. I'm surprised you avoided those.
Anyway, point being that the hypotheses advanced here, and quality of supporting reseach and analysis, is always in a state of flux.
I don't remember him on the Foster threads but I think I did avoid the others.
