Well, I think the site is crass - I would be very upset if a relative or friend were in there, even if they did, through a stupid act, cause their own death.
If there was a point - which I might assume there is - perhaps to the absurd number of deaths attributed to non-combat.
I think it most likely a phenomonen of the technology bias and effort, thereby, to reduce combat casualties that sees such statistics.
Approximately 50% of ALL US deaths during the Vietnam war are officially attributed to accidents - one of the biggest being 'friendly' fire.
Take away the combat casualty/technology issue, and this would probably be very much smaller, if only because combat related deaths would be so high.
Wherever there is human there is stupid.
I figure it may best be summed like this:
Neither race nor sex *nor nationality* possess any monopoly or moral highground with regard to dishonesty, stupidty, or down-right jerkism.
I have an IQ around 150, give or take. School was a breeze - and thus, very boring. I also stuck my finger in a light socket because I wanted to know what it felt like...

well, now I know.
