A regular person would be charged with murder, shooting an unarmed person with no disparity.
There are innumerable examples of lawful self defense shootings in CA. I'm not saying this is one of them, because I don't know what happened (I honestly think it looks bad on the surface), but your statement is nonsense and not accurate in any sense.
Not at all. All shootings involving death are given a murder change with proven self-defense being an 'affirmative defense'.
Just because someone insulted you and pushed you when you were holding your child is an affirmative defense to killing them when they were unarmed, if there is no disparity of force.
It may be different if you're a thug with a badge, off duty or not.
First, you have no idea that's what happened (a push and nothing else). Second, all shooting deaths are not given a "murder charge." All shooting deaths are considered a HOMICIDE. That is an entirely different concept than a murder charge and the fact you are conflating the two is evidence you should stop feigning knowledge of this subject.
There are myriad situations where shooting an unarmed assailent in self defense is justifiable and warranted.
It appears your desire for righteous indignation is overriding any ability to remain objective or considerate of the possibility you may not know everything required to form such a hard line opinion.
