She’s pleading not guilty, unless she changes her mind she won’t name any names as it implicates herself to do so.
Surely that depends on the questions being asked, you wouldn't want her to lie under oath?
If she is asked if she remembers an event a witness claims to have present at, she could quit easily drop names in her reply of others that where at that event. They in turn could be potential witnesses (if not already).
We will have to wait and see what happens. Its just a shame it's not on live TV.
