Bump.
As predicted by XJarhead and others.
I remember that discussion. It's tragedy waiting to happen.
I participated in that thread- on the "uninformed" side. IIRC I didn't suggest that troops, as SOP, should be allowed or encouraged to mix blank and live rounds- noting rather that in my experience troops often chose to carry live rounds with them, regardless of SOP.
Guess this event is a pretty strong arguement for discouraging that practice.
My sympathies to the dead marine, his family, and also the marine who killed him. very sad.
