Courts Address Second Amendment Limits on Sensitive Places, Felons, and Mental Illness

Why it matters locally: Federal court interpretations of Second Amendment rights, particularly concerning 'sensitive places' and restrictions on felons, directly influence how Florida's existing gun laws are challenged and enforced, impacting firearm regulations across the state.

Federal courts are actively interpreting the boundaries of Second Amendment rights, specifically examining firearm prohibitions in 'sensitive places' and restrictions on individuals with felony convictions or mental health commitments. These questions arise from the amendment's text, which states, 'A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.' The Supreme Court, in *District of Columbia v. Heller*, recognized an individual right to possess a handgun for self-defense within one's home. Justice Antonin Scalia stated that this ruling did not question 'longstanding prohibitions on the possession of firearms by felons and the mentally ill, or laws forbidding the carrying of firearms in sensitive places such as schools and government buildings.' The Court reiterated this stance in the recent *Wolford v. Lopez* decision, which invalidated a Hawaii law prohibiting firearms on private property open to the public without express permission. ### Sensitive Places Defining 'sensitive places' involves two primary questions: what constitutes such a place, and which locations justify restricting firearm carry. The Supreme Court addressed this in 2022's *New York State Rifle & Pistol Association v. Bruen*, noting that historically, few locations, such as legislative assemblies, polling places, and courthouses, completely prohibited weapons. Judges now look to these historical regulations when evaluating modern restrictions. In 2023, the U.S. Court of Appeals for the 2nd Circuit upheld New York's prohibitions on firearms in urban public parks, zoos, establishments serving alcohol, theaters, entertainment venues, and treatment centers. The court found that the government demonstrated a historical tradition of regulating firearms in such locations. However, the court did not uphold the regulation for places of worship, basing that part of its decision on First Amendment grounds. Separately, in 2025's *Schoenthal v. Raoul*, the U.S. Court of Appeals for the 7th Circuit affirmed an Illinois law preventing loaded firearms on public transportation. The court cited a historical tradition of regulating firearms in 'crowded and confined locations.' It also noted that such a regulation presented a temporary burden, allowing individuals to carry unloaded firearms. Other appellate courts, including the 3rd, 4th, and 9th Circuits, have also reviewed sensitive place challenges. These courts generally agreed that parks, healthcare facilities, and places serving alcohol qualify as sensitive places where firearm prohibitions are permissible, while striking down other provisions. ### Felons Challengers have also contested laws prohibiting felons from possessing firearms. Federal statute 18 U.S.C. § 922(g) restricts firearm possession for anyone convicted of a felony. Following the *Bruen* decision, the government must demonstrate a historical basis for disarming felons. The Supreme Court has not directly ruled on the constitutionality of felon-in-possession laws. However, in *McDonald v. City of Chicago* (2010), the Court reiterated that its *Heller* ruling did not question prohibitions on felons possessing firearms. Similar statements appeared in the 2024 *United States v. Rahimi* and *Wolford v. Lopez* decisions. In *United States v. Hemani*, also decided in 2024, the Court avoided addressing the general constitutionality of the felon provision, focusing instead on drug users. Lower courts have adopted differing approaches. In 2023's *United States v. Jackson*, the 8th Circuit upheld Section 922(g) as applied to a defendant with a non-violent drug offense felony. The court referenced the *Heller* assertion that such prohibitions are presumptively lawful and cited historical regulations that disarmed certain groups based on perceived threats to social order. The 2nd, 4th, 9th, 10th, and 11th Circuits have also taken a categorical approach. Conversely, the 6th Circuit in 2024's *United States v. Williams* required courts to evaluate the nature of the underlying felony. The court stated that history supports disarming individuals based on dangerousness, but judges should consider the specific attributes of the individual and their criminal record. While crimes like murder might carry an 'irrebuttable presumption of dangerousness,' others, such as fraud, would be more difficult to justify as a basis for disarming someone. The 3rd and 5th Circuits have also favored case-by-case analysis over a categorical approach. This circuit split means that the outcome of a Second Amendment challenge by a convicted felon often depends on the specific appeals court handling the case. Resolution of this divergence awaits further Supreme Court clarification. ### Mentally Ill Individuals Section 922(g) also prohibits firearm possession by individuals 'adjudicated as a mental defective' or 'committed to a mental institution.' Federal regulations clarify that 'committed to a mental institution' applies to involuntary commitments. This restriction has generated limited case law. In *Hemani*, the Supreme Court briefly noted that this prohibition 'involve[s] some manner of pre-deprivation process before an individual’s Second Amendment rights are lost,' without further elaboration. In 2025's *United States v. Gould*, the 4th Circuit addressed a challenge by a defendant involuntarily committed to mental health facilities. The court acknowledged the historical lack of explicit regulations regarding firearm possession by mentally ill individuals, attributing this to differing understandings of mental health in earlier centuries. However, the court identified historical precedents in disarming incapacitated individuals posing a danger to themselves or others, and disarming groups deemed 'dangerous.' The court concluded there was 'an unambiguous history and tradition' of disarming individuals with mental illnesses who posed a threat. Another unresolved issue is whether a lifetime ban for individuals with past mental illness is permissible, or if a process for regaining Second Amendment rights should exist. The 6th Circuit has found insufficient evidence to justify a lifetime ban for some individuals adjudicated mentally ill. In contrast, the 9th Circuit, citing scientific evidence of increased violence risk after involuntary commitment, upheld the permissibility of a lifetime ban. ### Conclusion Lower courts are navigating a range of Second Amendment challenges related to who can possess firearms, what types of arms are covered, and where firearms can be carried. Some observers view the Supreme Court's limited guidance as problematic, while others see it as a natural part of developing constitutional law. For now, appeals courts continue to interpret existing directives while awaiting further definitive rulings from the Supreme Court.
