Selling off a live army shell

Corruption takes many strange forms, and can cause very strange situations. However, this incident takes the cake. The Indian army has policies for disposal of its ammunition, and those do not allow letting its soldiers walk off with these shells and sell them for their personal benefit. So how do you account for the stupidity of this armyman and the scrap dealer to whom he sold it to?

Three people, including an Armyman, were killed and three others seriously injured when a shell exploded at a scrap dealer's shop in Punjab’s Muktsar district on Thursday.
Muktsar police chief Gurpreet Singh Gill said the Armyman had taken the shell to the scrap dealer in Mehna village to sell. “When the shopkeeper hit the shell with a hammer, it exploded, killing three people on the spot,” he said.

Shells have been known to be volatile. Bombs that were dropped during World War 2 in Europe are still seen as dangerous, and treated with as much care as live shells. How does one explain the concept of this army soldier trying to sell off a shell; one wonders about the caliber of our soldiers if she did not realize that a shell is volatile. And the policies of the army where a soldier could walk off with a shell during peacetime, and it is not missed.
