Not only does Tragos sound like an extremely well qualified gladiator, the Greek angle is notable. Trying to remember the details here, but as I recall, when Greer heard the initial medical testimony in Terri's case from which he rendered his deadly decision that Terri had no hope of rehabilitation and approved MS's petition to starve/dehydrate Terri, there was an interesting Greek connection.
Each side was allowed to produce the expert opinion of two medical witnesses. Of course, each side's medical experts produced entirely opposed opinions. Greer ordered a fifth, "independent" medical evaluation, by the court's own approved expert. He asked Felos for a recommendation of an independent expert (!!!). Felos recommended, and Greer accepted, a medical expert who happened to be a member of the same Greek fraternity to which Felos belonged.
From the looks of Tragos' credentials, I'd say we have the answer as to why Felos is now backing off from his public statements that the Schindlers assaulted their own daughter with a hypodermic needle! If that's what brought Tragos onboard with Terri's team, Felos must now be agonizing over his own immense stupidity. Ah...God does work in mysterious ways. This is GREAT!
