Thank you.
I think that's right. The thing to remember is that the Convention against Torture sets out a comprehensive program to prevent a unique problem. It's not necessarily based solely on the seriousness of the offence of torture, but it's based on the fact that when you have serious crimes being committed either by the state or with the consent of the state, it's more likely there's going to be impunity for those crimes, because the people who commit them are going to have the protection of state actors.
The convention sets out a number of unique policy requirements that are meant to eliminate the problem of torture and prevent the impunity. That's why we have the universal jurisdiction, the obligations to prosecute or extradite. That's why we have the prohibition on the admission of these statements into evidence. Those all rely on the very specific definition of torture that's set out in article 1. Once we get into a zone of confusing or enacting multiple definitions of torture, the program that's set out in the convention starts to become incoherent and it becomes difficult to define which incidents of what is defined as torture require the kinds of actions that are set out throughout the convention.
