A US judge has reportedly ruled inadmissible the confessions given by Khalid Sheikh Mohammed, the alleged mastermind behind the September 11th attacks. The decision stems from concerns regarding the treatment Mohammed received while in CIA custody, specifically allegations of torture. Details regarding the grounds for the ruling remain limited but suggest violations occurred during interrogation. This ruling significantly impacts the ongoing military commission case at Guantanamo Bay, where Mohammed and four other co-defendants face trial. Prosecutors now face challenges in building their case without this key evidence. The defense argued for the suppression of the confessions, citing coercive interrogation techniques. This development raises questions about the viability of prosecuting high-profile terrorism suspects through military commissions.
