I know Tommy from CCI. When I got posted in CCI in 92, he was already in the President's Office of CCI. He was friendly enough, socially, to me. I would not say he has many warm friends in the Sea Org, though. I have never seen him have any close friends. He is (or was) married to a European girl - Nadine Van Hootegen, now Nadine Davis. Last post I knew for her was the Qual Sec CCI. Again, my info is from about 2000 or so.
Yes, he has a Sea Org symbol tatooed to his upper arm. Not sure if it on the right or left side. It is a single blue color - the color they use for a single colored tatoo - kinda that blue-ish green color.
When I saw that BBC interview, I was suprized about Tommy's reaction. He must have been drilled and drilled to be like that. Normally he is pretty pleasant. I mean, he could get a little tough when he needed to, but not like what I saw in that video.
He seemed to me to be socially able to uphold a conversation, but never have or become deep friends with anyone. (That is normal in the Sea Org though).
If I remember right, he has had to do several PTS handlings related to his father, who is somewhat anti-Scn.
I wonder if it is easily researched by googling the mothers name and finding out about previous marriages. I think he does shipping or something on a large scale. Dang my memory sucks sometimes!
Hope that helps.
