If I kill someone, I AM "guilty" of a homicide. There is no presumption that it was justifiable..... I have to offer proof of that, or be prosecuted under the laws of my state.
THAT'S my answer to your first point.
Your second point is just a denial with no facts to back it up, so you are due no response.
Your third point was addressed by a specific case, which is what you asked for. I'm surprised you didn't look at the video since it's been posted several times in the last few days.
