The National Lawyers Guild (NLG) is a progressive bar association that has acted as the legal arm of social movements and the conscience of the legal profession. NLG's mission is to use law for the people, uniting lawyers, law students, legal workers, and jailhouse lawyers to function as an effective force in the service of the people by valuing human rights and the rights of ecosystems over property interests. They provide free "Know Your Rights" handbooks for encounters with law enforcement in English, Spanish, Arabic, Bengali and Urdu. The NLG is committed to the dismantling and abolition of all aspects of systems and institutions that support, condone, create, fill, or protect prisons, including jails, police lock-ups, juvenile detention facilities, immigration detention centers, involuntary psychiatric treatment centers, and other institutional settings in which people are held against their will. The Guild has engaged in numerous initiatives to promote an end to mass incarceration nationally and locally.
