As odd as it may sound, and since I don't remember it being mentioned in Broken's posts, I wonder if the advantage Monokuma mentioned could be the ability to essentially make someone else blackened in that time, even if they hadn't been the killer? I mean, it seems strange, as well as broken (heh) and all too tricky, but it's just a thought.

I have an idea how these loopholes could be exploited, but since I'm not sure if this crosses Broken's discussion rules I'll keep it under a spoiler tag.

[hider=BIG RULE ABUSE]Because rule 7 doesn't apply during the night of carnage, it is possible to murder as many people as you want to without triggering the trial sequence of the game, thus it is possible to weed out people until it is [s]four[/s] five people left, make an alliance with another to make a double murder outside of night of carnage, and then the two vote the other party to victory, or just wipe out the other players and make the last kill a proper murder.[/hider]
