Guy Montag Doe v. San Francisco Housing Authority is a lawsuit filed by the National Rifle Association the day after the United States Supreme Court decided in "District of Columbia v. Heller" that the Second Amendment to the United States Constitution protects an individual's right to possess a firearm for private use.
 The complaint against San Francisco challenges the city's ban of guns in public housing.
The Firearms Control Regulations Act of 1975 was passed by the District of Columbia city council on September 24, 1976.
 The law banned residents from owning handguns, automatic firearms, or high-capacity semi-automatic firearms, as well as prohibited possession of unregistered firearms. Exceptions to the ban were allowed for police officers and guns registered before 1976.
 The law also required firearms kept in the home to be "unloaded, disassembled, or bound by a trigger lock or similar device"; this was deemed to be a prohibition on the use of firearms for self-defense in the home.
 On June 26, 2008, in the historic case of "District of Columbia v. Heller", the Supreme Court of the United States determined that the ban and trigger lock provisions violate the Second Amendment.
Stephen P. Halbrook is a Senior Fellow at the Independent Institute and an author and lawyer known for his litigation on behalf of the National Rifle Association.
 He has written extensively about the original meanings of the Second Amendment and the Fourteenth Amendment (the latter as applied to Second Amendment rights).
 He has argued and won three cases before the US Supreme Court: "Printz v. United States", "United States v. Thompson-Center Arms Company", and "Castillo v. United States".
 He has also written briefs in many other cases, including the Supreme Court cases "Small v. United States" (pertaining to the Gun Control Act of 1968) and "McDonald v. Chicago".
 In "District of Columbia v. Heller", he wrote a brief on behalf of the majority of both houses of Congress.
 More broadly, his decades of research on the Second Amendment contributed to the intellectual foundation of the "Heller" decision.
 He has written many books and articles on the topic of gun control, some of which have been cited in Supreme Court opinions ("Heller", "McDonald", "Printz v. United States").
 He has testified before congress on multiple occasions.
 Halbrook’s most important scholarly contribution, however, was the book "That Every Man Be Armed", originally published in 1986.
 The book was the most thorough analysis of the legal history and original intent of the Second Amendment.
District of Columbia v. Heller, 554 U.S. 570 (2008) , is a landmark case in which the Supreme Court of the United States held, in a 5–4 decision, that the Second Amendment protects an individual's right to possess a firearm unconnected with service in a militia for traditionally lawful purposes, such as self-defense within the home, and that Washington, D.C.'s handgun ban and requirement that lawfully-owned rifles and shotguns be kept "unloaded and disassembled or bound by a trigger lock" violated this guarantee.
 Due to Washington, D.C.
's special status as a federal district, the decision did not address the question of whether the Second Amendment's protections are incorporated by the Due Process Clause of the Fourteenth Amendment against the states, which was addressed two years later by "McDonald v. City of Chicago" (2010) in which it was found that they are.
 It was the first Supreme Court case to decide whether the Second Amendment protects an individual right to keep and bear arms for self-defense.
District of Columbia v. John R. Thompson Co.
 Inc., 346 U.S. 100 (1953), is a United States Supreme Court case which began on April 30, 1953 over the validity of the local Washington Acts of 1872 and 1873.
 The Acts prohibited segregation in public places within the District.
 With the court’s support, the legal ramifications of the 1872 and 1873 Acts could once again be enforced.
 The case transpired during growing racial tension in the nation’s capital.
 Throughout Washington, the black community had grown tired of unfair treatment regarding housing, businesses, and education.
 But, change came soon enough through the courts.
 On June 8, 1953, the Supreme Court unanimously ruled that the segregating policies practiced by Thompson’s Cafeteria were illegal, marking a huge victory for the national black community.
McDonald v. Chicago, 561 U.S. 742 (2010), is a landmark decision of the Supreme Court of the United States that found that the right of an individual to "keep and bear arms" as protected under the Second Amendment is incorporated by the Due Process Clause of the Fourteenth Amendment against the states.
 The decision cleared up the uncertainty left in the wake of "District of Columbia v. Heller" as to the scope of gun rights in regard to the states.

 He is a Cato senior fellow and an author and pundit.
 Before becoming a lawyer, he was the founder and CEO of CDA Investment Technologies.
Hedgepeth and Williams v. Board of Education, Trenton, NJ, also known as the Hedgepeth–Williams case, was a 1944 New Jersey Supreme Court decision in a legal action brought by two mothers, Gladys Hedgepeth and Berline Williams, who sued the Trenton, New Jersey, Board of Education over racial discrimination against their children, Leon Williams and Janet Hedgepeth.
 It was a precursor to the "Brown v. Board of Education" case that prohibited racial segregation of school systems throughout the United States.

Williams v. Lee, 358 U.S. 217 (1959), was a landmark case in which the Supreme Court of the United States held that the State of Arizona does not have jurisdiction to try a civil case between a non-Indian doing business on a reservation with tribal members who reside on the reservation, the proper forum for such cases being the tribal court.
