Firearm regulations are laws and policies that govern the sale, possession, and use of firearms. These regulations vary widely by country and can include background checks, age restrictions, and licensing requirements. The goal is to promote public safety while balancing the rights of individuals to own firearms. In the United States, firearm regulations are primarily determined at the federal, state, and local levels. The Second Amendment of the U.S. Constitution protects the right to bear arms, but states can impose additional rules. Common regulations include restrictions on certain types of firearms, waiting periods for purchases, and mandatory training courses.
