This bill, titled the "Protecting Our Second Amendment Data Act," amends the Omnibus Crime Control and Safe Streets Act of 1968 to safeguard the personally identifiable information (PII) of individuals engaged in firearm-related activities. It mandates that entities receiving federal funding through several justice assistance programs must provide certifications regarding their handling of this sensitive data. Specifically, applicants for the Edward Byrne Memorial Justice Assistance Grant Program , discretionary grants for public and private entities, and COPS Grants must certify that they have not intentionally, accidentally, or otherwise knowingly disclosed PII during the previous fiscal year. This includes information pertaining to firearm registration, applications for concealed or open carry permits, and background checks related to firearm possession. The bill defines PII as information that can distinguish or trace an individual's identity, such as names, social security numbers, and biometric records, ensuring a clear scope for data protection.
