He was 72 years old! He probably needed a nap!
Another case of a person with a gun but without any knowledge of the laws.
Don’t shoot at a suspect running away.
Don’t touch, much less dispose of evidence (spent brass).
Not calling 911 immediately indicates to the cops that you don’t 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.
I have been that tired before...
