Earlier quoted context omitted.

Is this needed to make a claim? If I say that someone stole the Declaration of Independence, then I would only need to provide evidence it was stolen, not evidence that shows some particular person stole it. In this case, evidence of illegal shorts is what one would need to provide to back their claim, not evidence that a specific firm engaged in illegal shorts.
Okay, what's the evidence of illegal shorts?
