If there was a magic button in the world that killed someone every time it was pressed, I'd be much more concerned about getting rid of the button or enacting societal change to keep the button under protection than I would care about tracking down people that pressed the button. Sure, some degree of that is good to discourage it too, but if the button remains out in the open, easy to press, and pressed by more people than actually do get captured, then something isn't right.
