I think staffing is going to be very important. I won't repeat what Professor Roach said about the need to staff robustly and perhaps staff outside of the traditional public service career pattern, in terms of bringing in special advocates who are the only non-governmental experts who have really seen the inside operations of the security services. I think that's important.
More generally, again, I think the culture of the members matters. There is a huge literature in the United States about who makes a good legislative oversight committee member: it means skepticism without partisanship, and an open mind and asking hard questions. The membership will matter.
