According to the official explanation that the ACC provided NCSU but did not make public (looks like an NCSU anonymous source did, though): "
(t)hey were ejected for excessive demonstration on several calls as they came right up to the scorer's table. The policeman at the end of the FSU bench was warned that their continual excessive demonstration that incited the crowd would result in ejection".

The optics of the scene were that Hess flew off the handle and just picked these two guys and ejected them. But if he warned the police officer, it sounds like he identified a behavior he found problematic, and when it recurred he ejected them. This is, IMHO, a far different thing.
Furthermore. jumping up, encroaching the scorer's table, and inciting the crowd are all things people should have seen. and a police officer should provide a stellar witness that Hess provided warning that the former Pack player's behaviors were out-of-line (even if the officer did not pass the warning on to C&G).
This story should be a slam dunk to corroborate, I'm kind of surprised that it hasn't been. Unless, perhaps, the ACC/Hess and NCSU BOTH realize neither party has acquitted themselves well here, and just want to watch the whole thing die-- which it looks to me like is happening.
