HB 2514 revises Tennessee's firearms laws by removing the offense of carrying a firearm "with intent to go armed" in K-12 schools, school buses, and university properties (when posted). It prohibits carrying firearms in K-12 schools/buses if the person intends to go armed, while eliminating similar restrictions for universities and colleges. The bill also rewrites rules around handgun possession while intoxicated, adds new definitions for "firearm" and "deadly force," and creates a legal presumption that threatening deadly force to defend property against unlawful entry is justified. It establishes immunity from prosecution for using justified force, including displaying weapons, unless the person knew the individual was a law enforcement officer or caused injury to an innocent bystander. These changes directly affect individuals carrying firearms in schools, campuses, or during property disputes.
