Firearms and Ammunition - As enacted, lowers the standard for the use of deadly force to protect property. - Amends TCA Title 39.

HB 1802 amends Tennessee law to lower the standard for using deadly force when protecting property. It allows individuals to use deadly force against others committing trespass, arson, property damage (including livestock), burglary, theft, robbery, or animal cruelty if they reasonably believe it is immediately necessary and non-deadly force would risk death or serious injury to themselves or others. The bill explicitly prohibits using deadly force against someone facing away from the defender. This directly affects property owners and residents defending their homes or belongings against certain criminal acts. The law changes existing self-defense protections by expanding the circumstances where deadly force is permitted for property protection.
