Another case of a person with a gun but without any knowledge of the laws.
Dont shoot at a suspect running away.
Dont touch, much less dispose of evidence (spent brass).
Not calling 911 immediately indicates to the cops that you dont really care about a guy dying on your watch.
Either the shooter is totally ignorant of his responsibilities under the law or there is more to this story.
Also, beyond the initial call, dont talk to police. Second call to lawyer.
Yeah, lot of good points there.
