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.
At common law, an intentional unpermitted act causing harmful or offensive contact with the person of another. Battery is concerned with the right to have one's body left alone by others. Battery is both a tort and a crime. Its essential element, harmful or offensive contact, is the same in both areas of the law. The main distinction between the two categories lies in the penalty imposed. A defendant sued for a tort is civilly liable to the plaintiff for damages.
