there is no equivelence between Armstrong's Two Oswald Theory and the Lonsdale affair. Assuming the ID of dead people has long been an option for spies and criminals.
The de La Guardia twins were arrested and tried on drug trafficking charges - which may or may not have had a political motive concerning one of the other arrestees. I have searched for some indication that they were involved in spying and if so, that it entailed assuming each other's identity, and have found none. What exactly does Armstrong claim about them that he believes shows equivelence?
Bottom line -- if they were in fact spies, and if they did pretend to be each other as part of their spy activities -that at least makes some sense. They looked very much alike and shared personality traits and personal history. The theory that two unrelated boys - one noticably shorter and brighter than the other - were used in a lifelong project involving one pretending to be the other - and moreover, neccitating the use also of a doppleganger mother for the one dubbed "Harvey", is the stuff of z grade movies.
As for the files marked "Harvey Lee Oswald"... don't forget the one marked "Henry Oswald" -- maybe we should go for a triplet project? Or maybe there were other reasons for it. The work done by Bill Simpich may help clarify.
The Armstrong case for two Oswald's is a lot like the WC case for a lone assassin. It is built on often misunderstand, or deliberately reshaped circumstantial evidence - padded out with irrelvancies and bloated to a supersized burger for public consumption. Both can look appealing for those hungry enough for a solution. Just don't put the ingredients under a mcroscope!
The main difference is that whereas the WC never met an"Oswald sighting" it could accept - Armstrong never met one he could reject.
But both extremes were in support of a predetermined conclusion.
Greg, what about Armstrong's photos of 2 Lee Harvey Oswalds in school? (One was Harvey Lee Oswald.) And one of the Oswald's had a busted tooth in high school. And one had an inner ear surgery. Why did Marina walk up to the coffin before it was put on display and open one of his eyes to see the color? (Why else?)
I can't wait to read your book.
