The duty to retreat is not universal, however. For example, police officers are not required to retreat when acting in the line of duty. Similarly, some courts have found no duty to retreat exists when a victim is assaulted in a place where the victim has a right to be, such as within one's own home.[1] The Model Penal Code[2] suggests statutory language that also recognizes an exception to the usual duty to retreat when the victim of the attack is in his or her own dwelling or place of work. It is common to exempt a person's home or car from the duty to retreat, known as the castle doctrine.
Many states employ stand your ground laws that do not require an individual to retreat and allow one to match force for force, deadly force for deadly force. The Washington State Supreme Court, for example, has ruled "that there is no duty to retreat when a person is assaulted in a place where he or she has a right to be."
