Background: Leonard Peltier (born September 12, 1944) is a Native American activist, a citizen of the Anishinabe & Dakota/Lakota Nations, and member of the American Indian Movement (AIM). In 1977, he was convicted and sentenced to two consecutive terms of life imprisonment for first-degree murder in the shooting of two Federal Bureau of Investigation (FBI) agents during a 1975 conflict on the Pine Ridge Indian Reservation. Peltier's indictment and conviction have been the subject of much controversy; Amnesty International placed his case under the "Unfair Trials" category of its Annual Report: USA 2010. Peltier is incarcerated at the United States Penitentiary, Coleman in Florida.
Context: On June 26, 1975, Special Agents Jack R. Coler and Ronald A. Williams of the Federal Bureau of Investigation (FBI) were on the Pine Ridge Reservation searching for a young man named Jimmy Eagle, who was wanted for questioning in connection with the recent assault and robbery of two local ranch hands. Eagle had been involved in a physical altercation with a friend, during which he had stolen a pair of leather cowboy boots. At approximately 11:50 a.m., Williams and Coler, driving two separate unmarked cars, spotted, reported, and followed a red pick-up truck which matched the description of Eagle's.  Soon after his initial report, Williams radioed into a local dispatch that he and Coler had come under high-powered rifle fire from the occupants of the vehicle and were unable to return fire with their .38 Special revolvers. Williams radioed that they would be killed if reinforcements did not arrive. He next radioed that he was hit. FBI Special Agent Gary Adams was the first to respond to Williams' call for assistance, and he also came under intense gun fire; he was unable to reach Coler and Williams.  The FBI, BIA, and the local police spent the afternoon waiting for other law enforcement officers. At 2:30 p.m., a BIA rifleman fatally shot Joseph Stuntz, an AIM member who had taken part in the shootout. At 4:31 p.m., authorities recovered the bodies of Williams and Coler from their vehicles. At 6:30 p.m., they used tear gas to storm the Jumping Bull houses, where they found the body of a Native American, Joseph Stuntz. Stuntz was clad in Coler's green FBI field jacket, which he appeared to have taken from the agent's car. The two FBI Agents were later confirmed to have died on June 26, 1975. Stuntz appeared to have died later, during subsequent shooting.  The FBI reported that Williams had received a defensive wound to his right hand (as he attempted to shield his face) from a bullet which passed through his hand into his head, killing him instantly. Williams received two gunshot injuries, to his body and foot, prior to the contact shot that killed him. Coler, incapacitated from earlier bullet wounds, had been shot twice in the head. In total, 125 bullet holes were found in the agents' vehicles, many from a .223 Remington (5.56 mm) rifle.  Leonard Peltier provided numerous alibis, to different people, about his activities on the morning of the attacks. In an interview with the author Peter Matthiessen (In the Spirit of Crazy Horse 1983), Peltier described working on a car in Oglala, claiming to have driven back to the Jumping Bull Compound about an hour before the shooting started. In an interview with Lee Hill, he described being woken up in the tent city at the ranch by the sound of gunshots. To Harvey Arden, for Prison Writings, he described enjoying a beautiful morning before he heard the firing.
