Meaning of "Who Dunnit?" by Genesis

The lyrics of "Who Dunnit?" can be interpreted as a commentary on human nature and the tendency to deflect blame onto others. The repetitive nature of the lyrics reflects how accusations can be tossed around without any real accountability. The confusion and lack of clarity in the song suggest a sense of collective guilt, with everyone pointing fingers at each other but ultimately no one taking responsibility. The final revelation that the speaker did not do it could be seen as a sarcastic twist on the idea that truth is subjective and easily manipulated in society. The song could also be seen as a reflection on how truth and responsibility can be obscured in situations of conflict and uncertainty.
