A refugee aid and human rights activist for over 35 years, Farrell first traveled to the Thai/Cambodian border in 1980 at the end of the Khmer Rouge terror. In the following decade he took part in many aid missions and human rights delegations to El Salvador, Nicaragua, and Honduras. After one of them he represented the delegation in testimony before the U.S. Congress. In the same period, delegations took him to the then U.S.S.R., Paraguay, and Chile.

In 1988 he traveled to Egypt, Jordan, Syria, and Israel, exploring opportunities for peace in the Middle East. Returning to the Middle East in 1990, he followed that visit with a stop in Prague as part of a team of election observers for the first free post-Cold War elections in Czechoslovakia. A third trip to the Middle East in 1992 focused on medical programs for children. Later that year, on behalf of the UN High Commissioner for Refugees, he went to Somalia and Bosnia. In 1995, again with the UNHCR, he returned to Africa, this time to Rwanda, Zaire, and Tanzania.

In the late 1990s, with Human Rights Watch, he took part in a mission to the U.S./Mexico border areas investigating claims of abuse against the undocumented by U.S. Border Patrol agents. In 1999, again with an HRW investigator, he toured and interviewed prisoners at McAlester State Prison in Oklahoma, with special attention to its segregation and death row facility, the infamous H-Unit.

At the invitation of the Government of Mexico, in April of 2000, along with Board Chair Steve Rohde, he testified as a representative of Death Penalty Focus before the Inter-American Court on Human Rights in a case dealing with the Vienna Convention on Consular Relations and its application to non-citizens on death row in the United States.

In 2002 and again in 2004, he was part of delegations from the Center for International Policy supporting efforts to combat illegal logging in Central America, with a focus on Honduras and Nicaragua.

A life-long opponent of the death penalty and an advocate of prison reform, Farrell has visited prisons and been involved in death cases across the U.S. for over three decades.

He is the author of two books: “Just Call Me Mike; a Journey to Actor and Activist;” and “Of Mule and Man.”
