The alternative, clearly, was in the Stormont House agreement. Plus there is the additional learning from Jon Boutcher’s work on the Kenova investigations and inquiries, and the real desire among victims to make progress.
Of course victims are realistic about the chances of prosecution in some cases—what a lot of them want is often quite different—but the great thing that I have seen from talking to families who have been subject to investigations by Jon Boutcher under the Kenova system has been how it has been tailored and sensitive to the needs of victims, while being realistic about the prospects of prosecution.
