The reason we looked at it in this context was that it was relevant to the scope of our investigation of the economic and efficient management of resources. Security resources are among the key things the department manages.
We had looked at overtime previously. This time we were struck by the growing volumes of overtime and of what we saw, again, as an absence of a systematic process at the regional and national levels to monitor and manage that overtime and in fact control it. Our feeling was that it was not being adequately controlled. We couldn't see evidence of adequate control of it.
Overtime, everyone knows—we agree—is an inherent part of any 24/7 operation. At the same time, if you look at the rate of growth—it is a rapid rate of growth—it was increasingly eating into the overall budget of the organization, and that alone was sufficient reason to focus some of our audit attention on it, trying to understand better how it was or wasn't being managed and controlled.
