I was present at an unsuccessful attempt. A dissident took to the platform just as the meeting was about to start and loudly announced that the faithful and discreet slave were false prophets and that jesus needed to be given back his proper place. Attendents forcibly removed him and the police were called. they took him away but he was released as the congregation did not want to press charges.
recently I heard that he is back in the truth and doing very well. His dissident act was put down to mental illness
