Hmm I actually wanted to create a discussion thread about the following youtube video and then conclude with an answer to your question: "Are humans just animals?"
I strongly believe in Descartes. Humans are evil, dumb and animals. All these 3 points can be clearly seen in the following video.
Being an animal: Obviously the officers do not step in to protect the weak, they do not listen to their own moral instead they just comply with the group.
Being evil: They gain pleasure from the victims suffering (just look at those faces)
Being stupid: They provide evidence against them by filming the incident themselves oO ->Retards
But even if you look at it from a more biological POV. We share 95% of our genome with Chimpanzees and consider them animals. Pigs are so close to us, that we can use their organs as spares for our own! We have been, are and will be hairless monkeys for quite some time!
