The best way to recognize or celebrate the day is by education.  Finding out about the struggles and wrong doings of governments or organizations around the world that have abused citizens by false imprisonment or other things is part of helping bring awareness and making the world a better place.
 

Amnesty International is a global movement of more than 10 million people.

Amnesty International was founded in 1961 by Peter Benenson, a British lawyer. Peter wanted  to launch an appeal in Britain with the aim of obtaining an amnesty for prisoners of conscience all over the world. The stated mission of the organization is to campaign for "a world in which every person enjoys all of the human rights enshrined in the Universal Declaration of Human Rights and other international human rights instruments. By the mid-1960s, Amnesty International's global presence was growing and an International Secretariat and International Executive Committee were established to manage Amnesty International's national organizations, called "Sections", which had appeared in several countries. They were secretly supported by the British government at the time. Amnesty International is largely made up of voluntary members, but retains a small number of paid professionals. In countries in which Amnesty International has a strong presence, members are organized as "sections". Sections co-ordinate basic Amnesty International activities normally with a significant number of members, some of whom will form into "groups", and a professional staff.
