Good spot, Derek!

It obviously wasn't dead code. It was zombie code, resurrected dead code. SEC could have issued their ruling more appropriately on Nov. 1.

I had been wondering what had gone on and this says it all. However, I thought Knight Capital had gone out of business because of this incident. Apparently not so. The fine of $12m seems purely pro forma. I take it the SEC figured that the company had punished itself enough.
