Has she been subpoenaed yet? As far as I can tell, she hasn't. Also, it was the AG who said the staff didn't have to testify. At this point, it is turning extremely political and there's no reason to think it will ever become the "actual" investigation it once was back in June-July. If I were Palin, I wouldn't let anyone near these people until the election. The tone of the questions will be "when did you stop beating your wife?" and I would want no part of that.
Now, if they have cause to subpoena Palin, they should do it and be over with it. The more this goes on, the more it looks like a fishing expedition. They've had a ton of testimony and evidence gathered (had it back in June). If they having nothing at this point, I wouldn't expect Palin to help them out (esp in this climate).
The big point here is that the onus is on
them to prove she acted against ethical standards - not on her to prove her innocence (bolded for Flasch
).
