The use of deadly force by police is defined as "is the force which a person uses, causingâ??or that a person knows, or should know, would create a substantial risk of causingâ??death, serious bodily harm or injury. In most jurisdictions, the use of deadly force is justified only under conditions of extreme necessity as a last resort, when all lesser means have failed or cannot reasonably be employed." So this could be used in a instance when a perpetrator has a weapon and needs to be subdued before they harm another person.

In some states, the homeowner cannot use deadly force unless the intruder has a weapon.
Nondeadly force can be used to repel either a nondeadly attack or a deadly attack. Deadly Force may be used to fend off an attacker who is using deadly force but may not be used to repel an attacker who is not using deadly force.
