Remember how the U.K. experience started. As Senator Segal described in the quote that I read into the record, it started with a different structure, with more prime ministerial responsibility that was gradually devolved over time.
The advice from Senator Segal, but also the advice from the U.K. committee, is to start prudently, start cautiously, and allow the committee the time to earn its credentials, both in the public arena and among the security agencies that it needs to oversee. Gradually, as that credibility grows, then structures can be changed.
