Once again... Most of the investigation will consist of forensics, and proximity. (NO RACIAL INSULT INTENDED) If a White man is in his home and a black man breaks in at 4AM,and is armed, and the white man shoots him... It wont take rocket science to figure out what happened. You can swap races, and neighborhoods any way you want. You'd still get the same results.
The facts will be what they are. Some may even try to interpet the evidence to fit a particular scenario, but the facts dont change.
Has anyone ever actually see a citizen prosicuted for a self defense shooting in a home invasion?
As a criminal investigator... self defense shootings tend to be ground ball's.
