I disagree, the traditional prologue is outside the story, these chapter prologues are not.
Without the prologue, there's something lost, but that doesn't change the fact that the execution is part of everyday, "normal", life.
As for removing the execution, to do that you'd have to rewrite the whole chapter, not just simply decide not include it. So it's not the same thing. The execution is part of the story. The prologue is by definition outside of the story.
