Self-defense, self-defence (see spelling differences) or private defense is a “countermeasure” that involves defending oneself, one’s property or the well-being of another from harm.
Did ya catch that point?
The use of the right of self-defense as a “legal justification” for the use of force in times of danger is available in many jurisdictions, “but the interpretation varies widely”.
Lega Justification, and where do you suppose that happen,oh well that would be COURT.
To be “acquitted” [which means ARRESTED, and found INNOCENT at TRAIL or by Plea Bargain, which the police do not do] of any kind of physical harm-related crime (such as assault and battery and homicide) using the self-defense justification, one must prove legal provocation, meaning that one must prove that he was in a position in which not using self-defense would most likely lead to death or serious injuries. The threat of damage or loss of property alone is not enough.
What a minute folks hes stumbling, eyes rolling in his head, he’s holding his heart, Wait a minute folks hes coming back up, hes back up. Now did you catch this sentence; “one must prove legal provocation”
[meaning that one must “prove” that he was in a position in which not using self-defense would most likely lead to ,“death or serious injuries.”

And where does that happen? Oh right the Superior Court system of the state.
Wiki Pedia. course we may have some great Law Professors who would like to Bless us with their wisdom.
I know not the best reference in the world, But alas its does seem to shed some light on the “notion” of self-defense.
Physical self defense is the use of physical force to counter an “immediate threat of violence”. Such force can be either armed or unarmed. In either case, the chances of success depend on a large number of parameters, “related to the severity of the threat on one hand”, but also on the mental and physical preparedness of the defender.
Brief summary for our on-line attorneys, however, I wasn’t there and Thank God for that. A day in court IMHO of course would surely have resolved the Circus, likely lessened the reality of this guy spending of about 99-years in prison, and he probly would have received the so obvious needed help. But hey that would have required an arrest and avoiding every publicity hound in America weighing in.
Alas here we are.
