The development of all-Ireland policing links is a logical and completely practical proposal.
It was put forward yesterday (Monday) as part of an SDLP policy document but it also offers considerable potential to other political groups.
Closer cooperation between the PSNI and Garda in terms of both training and administration may help to make our new policing structures more attractive to republicans.
Unionists, for their part, should be able to see the value of an all-Ireland intelligence agency which targets criminality in both jurisdictions.
There is already a good understanding between the Assets Recovery Agency in the north and the Criminal Assets Bureau in the south, both of which have made a considerable impact.
However, formalising those arrangements, to counter the cross-border threat from drug dealing and other forms of organised crime, makes solid sense.
The PSNI already recruits extensively from all parts of Ireland, and members from a southern background can be expected to play increasingly high-profile roles in the years ahead.
There is also every reason to believe that strong consideration should be given to a candidate from within the PSNI when Noel Conroy retires as Garda commissioner.
A partnership approach to policing across Ireland represents the way forward, and deserves to be widely supported.
