The "Defense of Others" is a legal principle that allows a person to use reasonable force to protect another individual from imminent harm. This concept is often applied in situations where someone witnesses an attack or threat against another person and intervenes to prevent injury or violence. The force used must be proportional to the threat faced by the victim. In many jurisdictions, the right to defend others is similar to the right of self-defense. However, it is important to note that the defender must genuinely believe that the person they are protecting is in danger. This principle is often discussed in relation to laws governing self-defense, assault, and criminal justice.
