What this topic is asking
Topic 3.5 covers the Second Amendment right to keep and bear arms and how the Supreme Court has interpreted it. The College Board pairs this topic with the required case McDonald v. Chicago, which is also a key example of selective incorporation (Topic 3.7).
The right to keep and bear arms
The Second Amendment's text ties "a well regulated Militia" to "the right of the people to keep and bear Arms". The modern Court has read it to protect an individual right to possess firearms for lawful purposes such as self-defense in the home, not merely a collective militia right.
McDonald v. Chicago (2010)
The balance with public safety
The right is strong but not absolute. Governments may impose reasonable regulations (such as restrictions on certain weapons or on possession by certain people) without violating the amendment. The exam frames the topic as a balance between individual liberty and public order and safety, which connects directly to Topic 3.6.
How this topic connects across the course
The Second Amendment is the cleanest bridge between two ideas the exam tests repeatedly. First, it is a civil liberty: a limit on what government may do to individuals, like the First Amendment freedoms in Topics 3.2 to 3.4. Second, McDonald makes it a selective incorporation case (Topic 3.7), because the ruling's force comes from applying the right to the states through the Fourteenth Amendment. When a stimulus involves a federal gun law, you analyze the Second Amendment directly; when it involves a state or local law, you must route through incorporation. Keeping that fork clear is what separates a 4 from a 3 on a SCOTUS Comparison.
The topic also previews the balancing theme of Topic 3.6. The Court has been clear that the right is fundamental yet not unlimited, so reasonable regulation can coexist with a strong individual right. In an Argument Essay you can use this to show command of nuance: cite McDonald for the strength of the right, then concede that public safety justifies some regulation, then defend where you draw the line. Examiners reward an answer that holds both truths at once rather than treating the right as either absolute or freely restrictable.

A. Identify: the Second Amendment right to keep and bear arms, applied to the states through the Fourteenth Amendment's due process clause.
B. Explain the similarity: both involve a city ordinance that effectively bans handgun possession in the home, challenged by a resident.
C. Apply the holding: McDonald incorporated the Second Amendment against the states, so a city cannot ban handguns in the home; the scenario's law would likely be struck down.

An Argument Essay FRQ, 6-point rubric.
Thesis (1): e.g. "Selective incorporation appropriately protects fundamental rights nationwide, even though it limits state autonomy."
Evidence (up to 3): the Fourteenth Amendment's due process clause; the Second Amendment incorporated in McDonald v. Chicago; the Bill of Rights' original limits on the national government only.
Reasoning (1): explain how incorporation ensures rights do not depend on which state you live in.
Alternative perspective (1): concede that incorporation reduces state power to set local policy, then argue uniform protection of fundamental rights is worth it.
