Kunstler's resume:

He was a director of the American Civil Liberties Union (ACLU) from 1964 to 1972, when he became a member of the ACLU National Council.

Kunstler gained national renown for defending the "Chicago Seven" (originally "Chicago Eight"), in a five month trial in 1969-1970, against charges of conspiring to incite riots in Chicago during the 1968 Democratic National Convention.

Kunstler arrived in Pine Ridge, South Dakota on Mach 4, 1973 to draw up the demands of the American Indian Movement (AIM) members involved in the Wounded Knee incident.[43] Kunstler, who headed the defense, called the trial "the most important Indian trial of the 20th century", attempting to center the defense on the Treaty of Fort Laramie (1868).

In 1974-1975, Kunstler defended a prisoner charged with killing a guard during the Attica Prison riot.

Kunstler joined the defense staff of Assata Shakur in 1977, charged in New Jersey with a variety of felonies in connection with a 1973 shootout with New Jersey State Troopers.
