Ms Oonagh McPhillips:

I do not think I would have sufficient information. Obviously, the establishment of the divisional protective services units has been an innovation over recent years. I would imagine that there are swings and roundabouts in terms of the resources available. In terms of any unit I have, I know that you can have it fully staffed this week, but then somebody gets promoted, somebody takes leave and somebody gets sick. It is a constant battle to keep those units fully staffed and at the optimum degree.
