Holy shit, short bus. Their investigation into Weiss was because he was doing some pretty illegal shit that had nothing to do with michigan cheating. While investigating it, they could turn up evidence (that was unrelated to why they were investigating Weiss) and turn it over because it looks like something that is also potentially a violation, but had no connection with what Weiss was doing. I explained it using a very easy to understand example, I can't help you're too mentally deficient to understand.
