That incident was a brazen act of stupidity coming from those criminals who thought they can escape the teeth of law. Meanwhile, I think the buyer company has been complacent enough that they did little to ensure that the copper cargo would be accompanied by their own representative and the insurance papers verified for their veracity considering that the transaction involves a considerable amount of money. Imho.
commodity traders.. dont seek to trade to get delivery. they hold 7day contracts where if they dont sell it on day 8 it triggers a delivery to them.
so they play with 7 day contracts and always sell on day 7. meaning the next trader sells on day 7. meaning the next trader sells on day 7.. meaning for 21 days it doesnt move
with fast trading by commodity traders circulating the stocks. the goods can be held up in warehouses for years.
think about it.
13 people arrested... hmm.. 300 containers containing hundreds of thousands of tiles. all individually handsprayed... that takes a few months.. not a 2 day lay-over
by not triggering a delivery.. no one inspects the containers.. they just sit there doing nothing until a delivery is triggered
