In an interview with the Globe, McChesney, 51, a lifelong Catholic, said her office would not call for resignations of bishops judged to have failed to adhere to the abuse policy. Instead, she said, her office would notify the bishops' conference when bishops or dioceses appeared to be in violation of the policy.Asked whether she would welcome changes to the policy, McChesney declined to comment, saying it would be inappropriate for her to weigh in on the bishops' ''work in progress.''''I don't think I have anything I can add about what I'd like to see or not see. These aren't my norms; they're the norms the bishops developed. So they have to be what they're comfortable with,'' said McChesney, a former Seattle police detective who joined the FBI in 1978 and became executive assistant director of the agency's law enforcement services division.She also declined to take a stance on whether the policy should include a statute of limitations for child sexual abuse, another controversial issue since most of the hundreds of recent allegations of clergy misconduct nationwide are too old, under traditional canon law rules, to be prosecuted. 'That's really difficult to say, because I do know that memories can fade and it's difficult to prosecute cases that are old,'' McChesney said. ''On the other hand, these are very serious crimes, and so you have to weigh that.''
