The text describes the "Protecting Communities and Preserving the Second Amendment Act of 2024," which includes various sections such as improving the background check system, handling mental health records, increasing prosecution of gun crimes, and conducting studies on mass shootings. Additionally, it covers topics like firearm commerce and interstate transportation, as well as reporting and penalties related to firearm laws.

In this section of the bill, several key terms are defined: an "agency" follows the definition in a specific U.S. legal code, "covered firearms provision" refers to certain sections of U.S. law related to firearms, "NICS" stands for the National Instant Criminal Background Check System, and "relevant Federal records" are those that show if someone is not allowed to possess or receive a firearm under specific legal rules.

The section discusses changes to the NICS Improvement Amendments Act of 2007, including the authorization of $20 million per year for improvements from 2025 to 2029. It also introduces new accountability measures for grant recipients, prioritizing those without unresolved audit findings and modifying some eligibility requirements for these grants.

The section outlines the process for making Federal records available to the National Instant Criminal Background Check System (NICS). It requires the Attorney General to issue guidance on how these records should be identified and shared, mandates agencies to prioritize providing these records to NICS, and involves submitting reports on the implementation plans. The Attorney General will also settle any disputes over which records should be considered relevant.

The section updates the legal definitions related to mental health in U.S. law by clarifying terms like "mentally incompetent" and "psychiatric hospital." It specifies conditions and exceptions for individuals considered to have mental health issues within legal proceedings and replaces outdated terms in existing laws to ensure consistency.

The text amends Chapter 55 of title 38 of the United States Code to specify that a person cannot be considered legally mentally incompetent just because they are mentally incapacitated or unconscious, unless a judge or similar authority decides they are a threat to themselves or others. This change ensures that such a decision must be made by a judicial authority.

In cases related to the administration of certain laws and benefits, a person cannot be classified as mentally incompetent unless a judge or similar authority decides they are a danger to themselves or others.

The section requires various federal agencies to submit annual reports to Congress about their sharing of records with the National Instant Criminal Background Check System (NICS), and outlines how these records should be updated or corrected. It also mandates the Department of Justice to report yearly on firearms-related prosecutions, including details about cases where no charges were filed and outcomes of those that were prosecuted.

The bill requires the Attorney General to create the Nationwide Project Exile Expansion, a program in specific areas to increase the prosecution of gun-related crimes by coordinating with state and local authorities. It authorizes funding for prosecutors and agents and mandates yearly reports to Congress on the program's impact, including prosecution statistics and task force activities.

The bill establishes the Felon and Fugitive Firearm Task Force within the Department of Justice to focus on investigating and prosecuting convicted felons and fugitives who try to illegally buy firearms. It allocates up to $10 million annually from 2025 to 2029 for these efforts, with a small portion allowed for administrative costs, and the task force will dissolve after five years.

The Department of Justice and its agencies are prohibited from running operations that involve encouraging gun dealers to sell firearms to individuals suspecting the guns will be used illegally, unless a top official personally reviews and approves a plan with measures to prevent illegal transfers.

The bill proposes to amend Section 924(a)(1) of title 18 of the United States Code by changing the maximum penalty for lying when buying firearms from five years to five years generally, and up to ten years if the offense involves a specific type of violation.

Section 924(a)(8) of title 18 in the United States Code is changed by adding a reference to subsection “(n)” alongside the existing references to subsections “(d)” and “(g)”.

The section mandates a study by the National Institute of Justice and the National Academy of Sciences to investigate the causes of mass shootings, such as mental illness, violent video games, familial relationships, and bullying. The study aims to provide Congress with a report on these factors within a year, with a focus on understanding what drives individuals to commit such acts.

The section requires the Director of the Office of Management and Budget to report to Congress within a year about federal agencies' ammunition activities. The report must detail ammunition purchases, expenditures, stockpiles, usage, and future needs for each agency over the past year.

The section discusses amendments to the NICS Improvement Amendments Act of 2007, mandating that the Attorney General reduce the allocated funds to a state by 5% if it doesn't provide sufficient mental health records or have statutes in place to do so within 18 months of the enactment of a new law. If after five years the state still lacks such statutes, the reduction increases to 10%.

The section modernizes firearm commerce by allowing firearms to be transferred when someone is temporarily located in a state and updates how dealers can operate locations. It specifies residency rules for members of the armed forces and certain U.S. officers stationed overseas, considering them residents of multiple states for legal purposes.

This section amends U.S. law to specify that people are allowed to transport firearms or ammunition across state lines for any lawful purpose as long as they follow certain conditions, such as ensuring the firearm is unloaded and kept in a locked container. It also clarifies that individuals cannot be arrested or detained under state laws regarding transportation of firearms unless there is evidence of non-compliance, and it shifts the burden of proof to the government in legal disputes over these transports.

The section outlines the rules for transporting firearms and ammunition across state lines, allowing individuals who are legally permitted to possess these items to transport them as long as the firearms are unloaded and kept in a locked container or secured safely. It also states that individuals cannot be arrested or detained for transporting firearms unless there is evidence of breaking these rules, and if used as a defense in court, the government must prove otherwise.

The proposed amendment to Section 1701 of the Omnibus Crime Control and Safe Streets Act of 1968 requires the Attorney General to check for duplicate grants before awarding them. If duplicate grants are awarded, a report listing these grants and explaining why they were awarded must be submitted to the relevant Senate and House committees.

The Attorney General is required to establish or maintain firearms trafficking task forces in designated field divisions of the Bureau of Alcohol, Tobacco, Firearms and Explosives, including Houston, Phoenix, Dallas, and Los Angeles. Each task force must have at least 12 special agents and focus on investigating firearms trafficking, particularly looking for violations of certain laws.
