What this team of cockroaches is doing is becoming more and more obvious:
1) They personally have no evidence of anything at all. Only their beliefs and bogus stories ( strengthened every day by the echo chamber).
2) They are convinced that "one day, somewhere, Vic assaulted someone".
So from the beginning, they've been bluffing. By trying to make Vic believe that they had evidence somewhere.
That's why they're talking about a secret investigation. That's why they claim to be happy to go to court, that's why they refused the confidentiality agreement proposed by Vic (for the depositions).
And from the beginning, because of their unfounded belief, they think Vic will chicken out if they finally convince him that they have "evidence".
A little like parents could say to their child "We KNOW that you ate your sister's chocolate... Now admit it.... (so we can be sure and punish you without having a guilty conscience)".
