This legislation aims to enhance penalties for the use of incendiary devices, including the burning of the United States flag, when committed during Federal offenses. Congress finds that such actions pose a significant threat to public safety and Federal property, and that desecrating national symbols in connection with crimes amplifies the danger. The bill's purpose is to address the intent to provoke civic unrest, intimidate officials, or signal violent disruption through these acts. Specifically, the bill amends title 18 of the United States Code to add a new section imposing an enhanced term of imprisonment of not less than one year. This additional penalty applies to anyone who knowingly uses an open flame or incendiary device, including burning the flag, while committing a Federal offense involving property damage, obstruction of government operations, or public endangerment. A crucial rule of construction specifies that this section does not apply to expressive symbolic conduct protected under the First Amendment, provided it does not involve criminal acts or threats to public safety.
