And I have spent all of my life working with, and training animals, and I can definitely tell you that moose was not the aggressor... it was trying to escape a couple of clowns who dont have enough respect for others (and yes I include the moose as an other), just to provide themselves with kicks. As far as the moose popping its jaws or huffing, or a wolf raising it's hackles and showing its teeth, those are not signs of aggresion either... those are warning signs telling who ever, to back off and leave me alone. Anyone ignorant enough to misinterpt those signs deserves what they get. As far as an animal is genetically programmed or not, or it's driven by it's instincts, is like arguing about religion...no one knows what is true and what isnt if they havent experienced it...
