"Didn't Gibson tell Kerry he knew what went on because he was there, and Kerry kept interupting Gibson and saying he was wrong?
Am I mistaken, or was that Gibson?"
IIRC, it was Gibson. Not because I saw the interview, but I'm pretty sure GLGB posted about it, and I hope he'll correct me if I'm wrong.
I haven't followed the thread, but assume you're talking about the medal-throwing incident. Yes, I do seem to recall it was Gibson who confronted Kerry about that, telling him that he was there.
