Well, in fairness, just because Roux said he's going to present testimony, doesn't mean it will be persuasive.
Really.. when its all boiled down, the very best and most persuasive testimony that Roux could present that would portray all these witnesses who inconveniently imagined a womans scream WHILE THE SHOOTING was occurring ( dr Stipp), as raving loonies with wild imaginations, would assuredly be Oscar himself. Up on the stand, demonstrating how he can scream not only with skill enough to fool people that its a woman screaming, but at the SAME TIME, scream like a man would.
Because Dr Stipp heard BOTH at the same time a man AND a woman screaming..
I was thinking of those throat singers from Siberia, and some Innuit tribes who have this art down finely. and I wondered if Oscar had demonstrated this skill , quite a party piece , I would think, at any time previous to the murder??
