I find the movie to be a decent reinterpretation of Rashomon, as can be judged by the widely dispersed reviews that the film is about racism and justice system. The film is about how truth is perceived by story telling. The young man predicament is inconsequential. Although it is apparent he was guilty of silence or as an accessory to crime I believe is legal term. The director choose to conveniently leave out how he got his bike back. Hand waived all the conversation, for artistic licence , that would have ensued at the crime event itself with killers/robbers and in the court room later about how got his bike. To use a crude analogy , it's the same crime of the townsfolk of Auschwitz.( Don't assume that zoom on Aryan looking juror wasn't hand picked for a reason) At minimal the young man could have warned the owner. His inaction allowed a horrible crime. That said it was not a movie about justice system or race was it. It was a movie about power of story telling and perception. How folks interpret stories to fit their own realities. Btw this story has been told countless times. It was just as good a story on Gilligan's Islands missing lemon meringue pie episode. The real story is in the jury, which is us, the audience and thier reviews here and elsewhere.
