Your neighbor has a pit bull. Its a fairly well behaved pit bull and stays in its yard. It tends to snarl and snap when kids walk by, but for the most part...it stays in its yard. But you dont like the owner and you dont like the pit bull so one day you hang out by the fence after school. You start yelling at the dog, working it into a frenzy when the kids walk by. The dog breaks free and mauls three children walking by. Do you bear responsibility?
