The idea of interchanging is that some members of the Garda Síochána will go to the North and that members of the PSNI will come here for stated periods of time to carry out their duties. This is a terrific Bill which we take very much on its macro-merits. When it becomes law and the various groups start to move up and down, it will be interesting to see how many it will affect. I see that the Minister, by regulation, will bring forward that measure in the Bill. He will say what numbers will be seconded from our end. Those who go will volunteer and those who transfer from the North will, equally, be chosen on a voluntary basis but it will be interesting to see how many will seek to have that experience and bring the skills of their chosen vocation to bear upon an alternative environment. It will be different.
