That's a good point about Garibaldi's role in the Earth/Minbari War - I don't know if it was ever mentioned again! I assumed he was in the military at that point, but I never really put that together with him actually being in the war. I would guess that he never really saw any action, but that's just a guess.

And re: the cameras. They show up again in the 4th season, I can't remember the name of the ep right now but it's the one where ISN does a propaganda-laden story on the station after secession. I don't know if they show up in any other episodes... we'll have to keep an eye out!
