Really? Do you have a source for this information?
The guy with the loaded fanny pack needs to have a leash put on him or his wife shouldn't let him out.
He wasn't a danger to anyone. He was defending himself against charging dogs.
If he were the dangerous individual you make him out to be, why didn't the police arrest him for reckless endangerment for the negligent discharge of his firearm inside this 'safe middleclass neighborhood'?
Because he didn't shoot at a moving target charging at him which would have likely sent the bullet astray thus recklessly endangering the neighborhood.
Instead he shot down at a relatively stationary target a foot away from his feet that was barking at him -- a much safer and guaranteed shot.
