Oklahoma Self-Defense Force Calculated to Inflict Death or Serious Bodily Injury is a form of self-defense that is allowed in the state of Oklahoma. This type of self-defense is intended to protect individuals from threats of serious bodily injury or death by using force calculated to inflict death or serious bodily injury upon another. The types of self-defense techniques that are allowed are deadly force, such as the use of firearms, or non-deadly force, such as using physical restraint or warning shots. Under Oklahoma law, deadly force can be used in self-defense if a person reasonably believes they are in imminent danger of death or serious bodily harm, and they have exhausted all other reasonable means of escape. Non-deadly force, on the other hand, can be used if a person reasonably believes that they or someone else is in imminent danger of physical harm or property damage. In either case, Oklahoma Self-Defense Force Calculated to Inflict Death or Serious Bodily Injury must be used as a last resort and should be used only when there is a reasonable belief that the use of force is necessary to prevent the imminent threat of death or serious bodily injury.
