The Gods Must Be Crazy?

I'll be honest, I'm having trouble reconciling this. I really really want to laugh, despite the fact that two people died. I keep thinking: "what if they didn't know what an artillery round signifies?". But then again, if you live in a war-torn country that has faced revolution and insurgence repeatedly, I somehow think they've picked up on these sorts of things. Maybe this unfortunate accident really does belong in the realm of the rocket car or the bullet fuse told by the Darwin Awards.
