With the summaries out there of what people saw on the footage, what motivation does he have to continue to not release it?
If he says the summaries are lies, then he can release the footage to prove they are.
If they are indeed accurate, but he says the summaries are lies, by not releasing the footage he is confirming that the summaries of what people viewed are correct. The only reason not to release it would be because he doesn't want the footage to agree with the summaries of the people that viewed them.
He's basically in a double-bind. If what he is saying is a lie, then releasing the footage will verify he was lying and prove the summaries are correct. If he doesn't release the footage people will have to assume that the summaries are correct because otherwise he would release the footage to show they are false. So, not releasing the footage is a guaranteed loss, the only way for him to "win" is to be telling the truth and release the footage, but we know that is literally impossible/will never happen.
You literally can't win, Nick.
