I know you are not a blasé person, ShoootingStar, but as a military mom, I kind of feel the same way as Pax. I am generally a very liberal (very) person, but I think of the high tech aspect of war as something that might actually save my son's life.
Personally, unless you have actually been in a war, I don't think we can imagine what the people think like. I know my son says, "It's my job," when he is asked about stuff like this. He is incredibly level headed, been deployed to war zones 3X (and 2 others, that were not war zones), and no signs of PTSD.
I don't know why people (bystanders) would take pictures of dead people, like Pam describes. It just seems strange to me. What kind of need does that serve?
