I checked the video. It was rather inconclusive - however, my impression is that the dog was not behaving in an agressive manner. I own a very protective malamute/shepherd mix, and if she thought I or my wife were being threatened, she would not amble out of the car, she would be going full-speed in a line for the person's throat. That dog seemed to be meandering around - not the mark of a dog wanting to attack someone.
