The law on the use of lethal force is quite clear. "In the United States, a civilian may legally use deadly force when it is considered justifiable homicide, that is to say when the civilian feels their own life, or the lives of their family or those around them are in legitimate and imminent danger."

To require a person to prove that had they not taken action would have been killed it tantamount to being asked to prove a negative.
