While I think that the "rule" of multiple witnesses is a good one, it should not keep from the investigation into allegations of ANY Crime being commited.
What I've always wondered why this two witness rule doesn't apply to things like murder? Why only sexual abuse and rape?
I mean, if Joe Witness sees another JW shoot and kill someone, why don't the elders demand Joe present 2 eyewitnesses to "prove" his allegation? Think that would go over well with the police? "Gee officer I couldn't report the murder because I could not present 2 eyewitnesses."
Are accused or people on "trial" able to request a public trial with their accusers present?
Not at all. It is absolutely kept secret. No one, especially the victim, is allowed to take notes or make any recordings. The elders can ask any question no matter how humiliating, such as "Did you have an orgasm?" "Were you wearing underwear?" "Did you enjoy it?" and so on.
