The burden to prove that you were justified is on YOU
Not in every state. For example, after Harold Fish, AZ changed their law so that disproving SD is the prosecutor's burden.
Not quite correct, and it's a subtle, but very important, distinction. Even where the defendant does not have the burden of proving self defense, he still has the burden of producing evidence that all the elements of justification have been satisfied, i. e., making a
prima facie case. The prosecutor does not have the burden of disproving self defense unless and until the defendant has put on a
prima facie case of self defense. And if the defendant does not make a
prima facie case, he will not get a self defense jury instruction from the judge.
Since it was mentioned, let's look at cuurent Arizona law as modified as a result of the
Fish case.
Under 13-205A, Arizona Revised Statutes, "...
If evidence of justification pursuant to chapter 4 of this title is presented by the defendant, the state must prove beyond a reasonable doubt that the defendant did not act with justification...."(emphasis added)
Thus it is not sufficient that the defendant merely say he was defending himself or another.
The defendant retains the burden of presenting evidence that his conduct was justified under the applicable provision of Chapter 4 of Arizona Revised Statutes.
For example, under 13-404, ARS, "...a person is justified in threatening or using physical force against another when and to the extent a reasonable person would believe that physical force is immediately necessary to protect himself against the other's use or attempted use of unlawful physical force...."
And under ARS 13-405, "... A person is justified in threatening or using deadly physical force against another:
1. If such person would be justified in threatening or using physical force against the other under section 13-404, and
2. When and to the degree a reasonable person would believe that deadly physical force is immediately necessary to protect himself against the other's use or attempted use of unlawful deadly physical force....."
Therefore, the defendant claiming justified use of deadly force has the burden of putting on competent evidence that the requirements of 13-404 and 13-405, or one of the other provisions of Chapter 4, have been satisfied.
As a practical matter, if you claim self defense you will need to put on a convincing case of justification even if you don't have the burden of proof. You have admitted committing an act of extreme violence on another human being. This is something that most people, probably including most of the jurors, naturally find repugnant. You stand before the jury bearing the mark of Cain. The less convincing your self defense case is, the easier it will be for the prosecution to meet its burden of proof that your use of force was not justified.
