Self-Defense

In one sentence

The legal right to use reasonable force to protect yourself from harm.

Plain English

Self-defense is a legal justification for using force against someone who is attacking or about to attack you. The key word is 'reasonable'—the force you use must be proportional to the threat you face. Most states recognize a 'duty to retreat' in some situations, meaning you must try to escape if safely possible before using force. Some states have 'Stand Your Ground' laws that eliminate the duty to retreat and allow you to use force where you have a legal right to be.
