Provocation is merely a common factor, not necessarily in all cases. If I have to explain further, especially given the nature of this encounter and how it unfolded with its various factors, I’d rather direct you to other sources of legal definitions, etc.
You’d vote to convict for murder if you were on the jury, then? Even given the criteria, and circumstances, with beyond reasonable doubt being the threshold? Really? Think all jurors would? There you go. Voluntary manslaughter. Loong sentence.
