This’ll come up in the A32, but the agents did not immediately identify themselves as NCIS. Whenever they did, though, Weemer should have stopped.
NCIS agents did play the “recall” card though throughout the investigation. If an inactive Marine refused to talk, agents would say they could get him recalled for active duty. A nasty trick that isn’t true. NCIS agents don’t have that power. But it was an effective means of coercion.
I remember the 1st case I had heard of, one of the Hamandia cases, where 3 Marines swore NCIS changed their signed affidavits. I came in when prosecutor Piggot suddenly decided that he was a witness as well as a prosecutor - I don't remember who he had supposedly witnessed making a statement to NCIS or wtf business of his it would have been to be present for an interrogation, I just remember my jaw dropping at the absurdity of the situation.
That sort of crap has just gotten expotentially deeper since.
I think refusing to cooperate is going to be a growing trend unless the Marine Corps changes direction and stop offering up Marines to placate Iraqi and Democrat politicians.
