Well, this guy was barked at, and ran at while his kid was near. That is aggressive behavior, and all this whining about the poor dog is just "Sour Grapes."  The time to be concerned for the dog was when it was frequently barking at passersby, aggressively chasing  people, and obviously not suited to city living. If some of this angst was put toward putting it in a more suitable home, everyone would have been much happier. Deal with your dogs, people, or someone may do it for you.
