 In practice, this is going to make it very difficult to prove even purely unofficial acts. And Justice Sotomayor gives the example of a president who wants to murder his rival in order to stop him from passing bills. And you're not allowed to look at the fact that he's stood up and said that I want to murder my rival because that might be related to some sort of official act. So that's why, in practice, this may really make it extraordinarily difficult to prosecute the president for anything.
