Quote from marketsurfer:
That's called criminal fraud in the USA. You are mixing analogies--in an ill fated attempt to "prove" a point. any system can be interfered with by criminals. It has nothing to do with the subject. sorry, it doesn't work with me. surf
"Kerviel admits to exceeding his credit limits, but claims he was working to increase bank profits. He told authorities that the bank was happy with his previous year's performance, and was expecting to be paid a Ë300,000 bonus."
Tell me that's something but greed.

In the case of Kerviel it was not clearly a fraud, all he did was executing positions beyond his allowed limits, trading itself was not fraudulent.
