Rarer than any metal, any mineral, so rare that if you scan the entire earth, all six million billion billion kilos or 13,000,000,000,000,000,000,000,000 pounds of our planet, you would find only one ounce of it?
Self-defense is a common defense by a person accused of assault, battery, or homicide. The force used in self-defense may be sufficient for protection from apparent harm (not just an empty verbal threat) or to halt any danger from attack, but cannot be an excuse to continue the attack or use excessive force.
Assault and battery are offenses in both criminal and Tort Law; therefore, they can give rise to criminal or civil liability. In Criminal Law, an assault may additionally be defined as any attempt to commit a battery. At Common Law, both offenses were misdemeanors.
