Mr. Martin Callinan:

The people in the cold case unit are not confined to doing all the work themselves. When they review a case, they will identify a dozen, two dozen or four dozen issues that might require further clarification or investigation and that is farmed out to the local people who carried out the initial investigation or may be sent elsewhere to pursue those lines of inquiry and report back. So it is wider, with a dedicated unit looking at specific issues but then personnel in the force in general available to it to carry out that work.
