Leonard Peltier has spent over 35 years in prison for a crime he did not commit. Prosecutors and federal agents manufactured evidence against him (including the so-called "murder weapon"); hid proof of his innocence; presented false testimony obtained through torturous interrogation techniques; ignored court orders; and lied to the jury. People are commonly set free due to a single constitutional violation, but Peltier—faced with a staggering number of constitutional violations—has yet to receive equal justice
