What shared question connects the cases?

Brief each case and mark the right, governmental level, relevant facts and holding. Explain why a government-level distinction matters even when a right's name is familiar.

Create an annotated comparison using the supplied excerpts and context. Explain one claim, one supporting detail and one limitation in your own words. Use a diagram with a text description if helpful.

Gideon and McDonald: applying rights to states

Selective incorporation concerns applying Bill of Rights protections against states through the Fourteenth Amendment. Gideon involved counsel for an indigent defendant in a state felony prosecution. McDonald involved the Second Amendment right recognized in Heller and local handgun restrictions.

Read the primary evidence

Gideon v. Wainwright, opinion

US Supreme Court; Justice Hugo Black · 1963-03-18

Short primary-text excerpt: “lawyers in criminal courts are necessities, not luxuries”

Gideon had been denied appointed counsel in a Florida felony case. The decision applies a fundamental right to counsel to the states through the Fourteenth Amendment.

Read the original. Historical public-domain text or US federal judicial/government text. Only a short excerpt is included; modern editorial material is not reproduced.

McDonald v. Chicago, opinion

US Supreme Court; Justice Samuel Alito · 2010-06-28

Short primary-text excerpt: “the Second Amendment right is fully applicable to the States”

A challenge to local handgun restrictions asked whether the right recognized in Heller applied to states. Justices supporting the result differed over the Fourteenth Amendment’s route; applicability is distinct from every regulation’s validity.

Read the original. US federal judicial opinion. Short excerpt only; modern host editorial material is not reproduced.

Work through the comparison

Create a chain from a named protection to the Fourteenth Amendment and then to state action. Do not confuse applying a right to states with declaring every restriction invalid. In McDonald the justices supporting incorporation did not all use the same constitutional route.

Build your argument

Brief each case and mark the right, governmental level, relevant facts and holding. Explain why a government-level distinction matters even when a right’s name is familiar.

Use a compact table with one row per source: what it claims, the specific support you can identify, its intended audience or procedural setting, and a limit. Preserve your first answer before revising. The supplied context supports the guided task; deeper reading of linked originals extends it.

Check and transfer

What shared question connects the cases?

After committing to an answer, inspect the feedback and apply the reasoning to this changed situation: A case establishes that a right applies to states. A new state regulation is challenged. What remains?

Limits

Gideon’s felony-counsel holding is not a complete guide to all civil or criminal representation rights. McDonald does not resolve every question about firearm regulation.

AP framework connection

Fall 2026 AP US Government CED connections: 3.7.A, 3.8.A. Practice SCOTUS application: record facts, issue, holding, reasoning and result, then explain why the changed facts in the transfer do or do not fit the analogy. These are authored practice tasks, not College Board questions or proof of complete framework coverage.

Independent inquiry

Read the linked original beyond the short excerpt and document the section or page used. Compare the main reasoning with a rival interpretation or dissent, explain the historical context and defend a limited conclusion. Clearly separate your judgment from the source’s claim.

Worked example

Create a chain from a named protection to the Fourteenth Amendment and then to state action. Do not confuse applying a right to states with declaring every restriction invalid. In McDonald the justices supporting incorporation did not all use the same constitutional route.
