Firearms and Ammunition - As introduced, lowers the standard for the use of deadly force to protect property; specifies that deadly force does not include the display of a weapon, the brandishing of a weapon, or the use of force in circumstances that do not result in death or serious bodily injury. - Amends TCA Title 39.

HB 856 (Tennessee House Bill 856) would amend Tennessee law to lower the standard for using deadly force in property protection cases. It allows deadly force to prevent property crimes like trespass, theft, or burglary if a person reasonably believes other methods would fail or risk death/serious injury to themselves or others. The bill specifically defines "deadly force" to exclude merely displaying or brandishing a weapon, or using force that doesn’t cause death or serious injury. These changes directly affect property owners and law enforcement responding to property-related incidents under Tennessee Code Annotated Sections 39-11-614 and 39-11-106.
