The little I know, I do think not all accusations are true. But why do you think a Rebbe who says is innocent will step away from his job AUTOMATICALLY casting suspicion upon him? No one will do want to step away nor will administrations want to send away innocent people, even temporarily.
Now what about a famous personality who is a therapist? Do you think he’ll just shut his business down until the matter is “investigated”? So how do you propose letting people know someone is under investigation and MAY be a threat to society while doing it all quietly and not letting people know about it?
