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.
In the context of personal injury law, assault and battery are intentional torts (wrongs) that can form the basis of a lawsuit in civil court. In a typical case, the victim of an assault and/or battery sues the offender, seeking compensation for injuries and other damages stemming from the incident.
