If this were so "dubious"... then why the video evidence of the coaches taking said junior analyst's words and directly translating them to on-field calls?
I'm also looking at it like this; let's pretend Harbaugh didn't "know". Somebody ( the OC and DC) had to verify this little shits work, because they wouldn't just fly off cuff and call a check pre-snap on hunches from a low level staffer. Meaning, at minimum, THEY knew this information and scouting was likely illegally obtained.
At which point, if they suspect a violation has occurred, are they not required to report it? Even then, I'm treating it like receiving stolen property. If you receive stolen property, if there's any evidence to suggest you intentionally and/or willfully ignored where it came from, you can be held criminally and financially responsible along with whomever did the stealing.
Can we explain how this is any different than my example?
