In a recent development in Japan, three investigators working on the Big River's wrongful conviction case have once again evaded prosecution, as stated in a Japanese headline. The decision, made by the Prosecutor's Office, has triggered considerable societal debate over accusations of investigative misconduct. The headline does not reveal the timing or location of the case, but it emphasizes the repeated non-prosecution of the three investigators, underscoring the long-lasting contention surrounding this case.

In Japan, wrongful conviction cases like the Big River's garner public attention because they challenge the integrity of the law enforcement and judicial system. Such cases also provoke discussions about the balance between the need for truth and justice versus the rights of the accused. The main social and legal values involved in this case include fair investigation, assumption of innocence until proven otherwise, and accountability of law enforcement agencies.

In the U.S. and the E.U, similar issues related to law enforcement and judicial procedures are handled with equal seriousness. Public opinion and media closely scrutinize such cases, prompting reforms when necessary. Differences exist in the legal frameworks and systems of checks and balances, but in all these regions, upholding the rule of law and ensuring justice are paramount principles.
