Crimes: terrorism; making terrorist threat or false report of terrorism; modify. Amends sec. 543m of 1931 PA 328 (MCL 750.543m).

HB 4600 amends Michigan's law on terrorism threats and false reports, specifically modifying Section 543m of the Penal Code. The bill clarifies that making a threat of terrorism (even without intent to carry it out) or knowingly reporting a false terrorism incident can be prosecuted as a felony. It removes the defense that a defendant lacked the intent or capability to commit the threatened act. This law directly affects individuals who make threatening communications about terrorism or falsely report terrorism incidents, with penalties including up to 20 years in prison or a $20,000 fine. The bill was introduced on June 10, 2025, and referred to the Judiciary Committee.
