Repeating the same thing over and over will not make it any more accurate.There really is no additional complication. In all murder trials, an affirmative defense has to be mounted. That affirmative defense, if it is in fact self defense must prove that the use of deadly force was justified. The gun is nothing but a misdirection. Just as a type of knife used in a knife death or a bludgeon in a bludgeon death.
In almost every single gun self defense case, an expert gun witness is called by both the defense and the prosecutor.
there really is no additionalmoney involved. It will be the exact same money no matter what the gun looks like.
