Yes. I know it's an academic's prerogative to change his or her mind, but I still agree that there are a number of different considerations that could be legitimate to take into consideration. That's what makes it so difficult for someone in this role, such as an Attorney General or a DPP, to ultimately have to balance and come up with an action one way or another.
I agree that the public interest is not a singular thing. It has a number of different dimensions. We've seen cases where questions of national security become the dominant interpretation of the public interest, but we have also seen other older cases. There are English cases involving questions of prosecuting strikers, for example, in the context of labour relations strife. Those decisions about whether or not to prosecute in that context have also been seen as upholding a definition of the public interest.
