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.
Simple assault, usually charged as a misdemeanor, is the least serious form of assault. It involves minor injury or a limited threat of violence. In states where assault is a physical attack, pushing someone or slapping someone in an argument are instances of simple assault. Where the law defines assault as threatening behavior that puts another in fear, threatening to punch someone would be a simple assault.
