Easy answer to your question, OP:
its because lett, morris, losch, herd, jackson, sanderson and what's-his-name will NEVER sit in the hot seat themselves. They simply ignore summons and refuse to appear. They'll let the elders & co take the heat (and if they fuck it up, I'm sure they'll answer for it later!)
i wonder what's going to happen to the sister who testified about her abuse today. She's still technically a JW believer! Imagine the fallout when or if she's DF'ed for her testimony.
