It's the sort of twist no screenwriter would dare invent: "Free Leonard Peltier," a persuasively well-researched and often infuriating documentary about the American Indian Movement activist convicted nearly a half-century ago of killing two FBI agents,

The warning comes after the joyous twist of clemency for the Indigenous activist, as shown in a Sundance film premiering Monday

Jesse Short Bull and David France's documentary tells Peltier's story all the way through President Joe Biden's commutation.

Sundance: Jesse Short Bull and David France's documentary about the American Indian Movement member who was imprisoned since 1976 for killing two FBI agents is a disappointment.

The 11th hour clemency of Leonard Peltier has touched off a wave of joy, but it also brings pain to those who believe he should remain in prison for murder.

The commutation will allow Peltier, who has long maintained his innocence in the killing of two FBI agents, to spend his remaining days in home confinement.

President Biden's decision to commute Leonard Peltier's sentence after nearly five decades of imprisonment represents a significant shift in federal-tribal relations.

Biden commuted the life sentence of Indigenous activist Peltier, who was convicted in the 1975 killings of two FBI agents.

Former President Joe Biden commuted the life sentence of Indigenous activist Leonard Peltier, who had been imprisoned for nearly 50 years, on Jan. 20.

In the final hours of President Joe Biden’s term, he granted Leonard Peltier clemency through commutation, allowing him to serve his life sentence at home on the Turtle Mountain Indian Reservation in North Dakota.

Leonard Peltier has his life sentence commuted by President Biden during one of his last acts in the White House.

This is something that we always prepared for," producer Jhane Myers told Yahoo Entertainment about the documentary's contingency plan.
