Policing change was always going to be a process rather than an event. The SDLP is an active and robust player in driving the change. Sinn Féin, on the other hand, has thus far not come on board the new policing dispensation. I respect its right to make its own judgment in that regard, provided it does not create a chill factor for others who wish to make a different decision. I welcome the fact that Sinn Féin has expressed a wish to come on board when, according to its own criteria, the appropriate threshold has been established. The sooner that happens the better for the overall health of the peace process, since the sight of young republicans in PSNI uniforms might be the most compelling and reassuring evidence that the war is indeed over.
