Here is the thing. Yes, there is some evidence against scott. But ultimately it is a wifom. While he bears investigation(which I will get to in a moment), it is not much.
Diaz has lied. He has posted poorly. He has convinced many people to name-claim with no votes against them and under no compulsion while we know that one wolf (who died skillfully at the hands of absoltrainer) became more powerful because a specific named person died. He has led the town on a witch hunt based simply on a specific reading of an amibigous mod post. Furthermore, on this witch hunt, the seer has been ousted on day 3. Furthermore, he cleared HIMSELF from being included in this witch-hunt by supposing that it would have been unnoticed if he hadn't brought it up.
Scott has voted for a wolf. And has been brought into a wifom by a wolf.
I don't see the conundrum.
As for investigating scott, I think that omega should target a willing person out of a pool of willing people to assist in targeting scott. That way someone else states the results, omega goes unknown, and if they refuse to work with him he comes out and calls wolf on them and gets priested.
