this point, I think there is definitely a red line. Judge Fischer should not be involved any further in the criminal case.
If not before, certainly after issuing the search warrant, Judge Fischer should have recused herself, and handed any future hearings and the trial itself off to another judge.
Would you think it's fair that the same judge you had a professional conflict with, gets to judge your defamation trial, be the subject of your highly inflammatory invective & criticism, and then subsequently the same week as your criticism, issue a criminal search warrant for your house and person, and then preside over your criminal trial too?
