Mr. Palin told the newspaper he feared for his wife’s safety and said Trooper Wooten had made threats against her and her family. The governor has acknowledged inquiries by her staff to the Public Safety Department but said she played no role in them. To demonstrate she welcomed the inquiry, Mrs. Palin asked the state attorney general to look into the accusations as well.
I believe from this report, Palin isn't worried about the investigation.
