What I am trying to say is that in a high density suburb such as this, most of the people in the immediate area would not be standing within 40 feet of the victim. LOL! I don't know, maybe they were.....
Timing is another issue. You'll actually hear the crack BEFORE the report, and that will tend to confuse non-shooters to no end.
And in your typical strip-mall area, with all those hard surfaces for the sound to reverberate off of--if you ask 10 witnesses where they think the shooter was, you'll get 11 answers.
