I think other witnesses' at the coffee shop may prove more reliable. We have heard nothing of "Polygraph testing" - nor should we. But they are common place - FBI (quantico), Homeland security, CIA... & just about every police force around the world, uses them. Not kidding. I don't think this info would be available to us. If MS was alone at the coffee shop, I think team Rosann would know it. Australia is not behind the rest of the world - police don't go on spouse's alibi alone. There needs to be more concrete evidence, such as other witnesses.
