Interesting point, Girl and I think you’re correct.
There’s no doubt that there’s at least the appearance of UCI.
That puts it right back to whether it was appropriate for Gen. Mattis to have chosen Col. Ewers as his legal advisor when Ewers investigated the incident early on and then tesified in Art. 32 hearings knowing that Gen. Mattis had to read and thoroughly study the transcripts from those hearings.
In this light I don’t believe it was appropriate.
