I know you like to twist or otherwise ignore your own rules, but rule seven--the rule that leads us to an investigation and this game show trial--refers to murder. Murder is premeditated. Lucina's case was an act of self-defense. Tsurugi's was a more complicated case, but it can be argued that if he was in a fugue state, it may not have been 'him', nor can we prove it was premeditated.

A murder is death, but death need not be murder.

So I pose the question: does rule seven count for any non-Overseer death, or specifically murder?
