... I don't think we've seen the last of Rudolph. I also don't think that any trial will be either that simple or that straight forward simply because both sides, i.e. the supernatural world and the vanilla muggle world want to put that genie back in it's bottle.. Which means a lot of testimony won't be allowed or changed...
I don't think we've seen the last of Rudolph, either.
But I think he's going to continue to be a low-grade asshat.
There won't be a trial. There probably won't even be any formal charges.
I think Harry was the only witness, and I
don't think he's going to file a police report on the incident. No body.
I expect Murphy is only one of
thousands from that night who officially are "Missing Persons" (without even a "presumed dead," because the gov't officially isn't admitting there was an assault by monsters, some of whom simply ate dead bodies).
