If I see a row of coffins, how does anyone but the military itself know its your relative in there? Up until Bush, the military always allowed publication of such photos. You do, of course, have the right to restrict media and photos at his particular funeral.
I'm sorry you lost someone, and we all owe him a debt of gratitude that can't be repaid. I wish I were still doing honor guard so I could have the honor of showing respect in that way for these soldiers.
Exactly which war did the military "always" allow these photos? I was in Viet Nam, but had never heard that pictures were allowed. All 50+000? I think not.
