It's like a 3-stage process
WW2 - newsreels.
Vietnam - TV in the living room
Iraq et al - broadband video on your personal computer screen.
Somehow, the computer seems more intimate to me, than the TV. Maybe because I rely on it so much, as a portal to the rest of the world. (And also to catalog and play all my music.) - So, maybe that's why I was being so precious. I can manage violence OK but would rather be warned if something nasty is about to appear on my monitor.
In the end though: No big deal. Just a gratutious attempt to keep "TB" on his toes ;)
