I'll be a bit surprised if he doesn't file a civil action against Dr. Das, though not entirely. A bit, because the suits are not filed with any expectation that there will be a response; he wants to claim that his detractors wouldn't even bother to fight the charges. But not entirely, because it's possible that Dr. Das would retain counsel and respond, and that would mess up the ploy quite a bit. I don't believe that Evans wants to be questioned as part of any legal action, because his confession video exists, and it would require him to either admit to the court that he committed a criminal offense, or deny it and weaken his credibility significantly.
And that latter part makes it particularly amusing when he tries to make it seem as if Kim has painted herself into a corner with her refusal to give him info on her legal career.
