Seems like a good sign to me as well. And if the case is judged on ROE, we win.
Obviously, the prosecution didn’t feel enough confidence in their case without cooking up a deal with Mendoza. So they don’t think they can win on an ROE basis alone.
We still don’t know if the IO is dismissing Mendoza’s testimony or not, however. I would hope so. But he may have heard all he needed to hear during the hearing so is not asking for further arguments about it.
A really asinine statement from LtCol Atterbury and like others here have noted probably didn't help his case with LtCol Ware. Atterbury's sensationalism and irrelevant questions and statements have not gone unnoticed by Ware, thank goodness Ware is a man who uses common sense.
