Thinking along the same lines.
The pin was pulled and the egg was tossed.
The spoon should have came off.
Might be some kinda home made weapon.
Made me scratch my head when they said that a Georgian just walked away with it.
Thoughts??
Dud?
My first thought is along the lines of the old joke. Terrorist holds grenade in weak hand, pulls pin with strong hand, then throws pin. Standing there with grenade still in hand.
Honestly, my guess is it wasn't a grenade that was thrown.
