So...rent-a-cop was "shouting" at the dog's owners. Couldn't he have been a bit more CIVILIZED in communicating his demands, instead of being Mr. Macho with a badge and loud mouth? The dog was simply reacting naturally...shout at his humans and OF COURSE doggie will get protective. Doesn't matter if it's a pit bull or a poodle. These rent-a-cops need to learn professionalism.
