A Spanish judge has launched an investigation of “systematic” torture at the Guantanamo Bay prison. On Wednesday, Judge Baltasar Garzon said he would probe the “perpetrators, the instigators, the necessary collaborators and accomplices” to the torture of Guantanamo prisoners. Spanish law allows it to claim jurisdiction because five citizens or residents say they were tortured while imprisoned at Guantanamo. Garzon’s probe is unrelated to a separate investigation of six Bush administration lawyers who authorized the torture carried out at Guantanamo.
