What did the Supreme Court rule in Brown v. Mississippi regarding confessions?

In Brown v. Mississippi, the Supreme Court ruled that confessions obtained under duress, particularly through physical violence or threats, are inadmissible in court. This landmark case highlighted the importance of protecting individuals from coercive interrogation techniques that violate due process rights. The Court found that the confessions obtained from the defendants were administered through extreme brutality and intimidation, raising serious concerns about the reliability and voluntariness of such admissions. Therefore, the ruling reinforced that for a confession to be valid and considered in a court of law, it must be voluntary and not obtained through unconstitutional means. This case set a significant precedent in protecting the rights of defendants against oppressive interrogation practices.
