Policemen and women are often leaders and quite influential in their communities. It is important that the PSNI members who will participate on secondment to the Garda create a positive effect on their own communities when they go back and that they help bridge the gulf between North and South. Such interaction generates mutual understanding. I have seen it operate in other arenas where we have exchanges, such as twinning, where it has been positive in changing attitudes and outlooks for the better. This is healthy and desirable and essential in the context of the divisions in Northern Ireland and the division between North and South.
