DHL Core Values under threat!

German police get a disc with heaps of dodgy dealings data on it. Zumwinkel, boss of Deutsche Post (and DHL), is first to be caught for non-payment of 1m Euros in tax and for syphoning the money off to a foreign bank.
His pay without bonuses, shares, pension supplements etc is well over this figure.
Why do they do it, people like this? It’s like stealing sweets from a sweet shop – when he could buy the sweet shop any time he likes!
