In 1977, when he was 25-years-old, artist Tom Otterness adopted a shelter dog, chained it to a fence, and shot it dead for an "art" film he called "Shot Dog Film." In 2008, he apologized, saying, "As you must understand this is a very difficult and painful situation for me. Thirty years ago when I was 25 years old, I made a film in which I shot a dog. It was an indefensible act that I am deeply sorry for. Many of us have experienced profound emotional turmoil and despair. Few have made the mistake I made. I hope people can find it in their hearts to forgive me." Not everyone has.
