premise: Many floppy-eared dogs head toward the direction of the camera while bystanders look on. hypothesis: A crowd lunges at dogs that are running from a camera man.
contradiction: People who look on are stationary, but a crowd that lunges is moving.  If " camera man " refers to the person who took the picture, then " the camera " is being held by the "camera man", so " head toward the camera" and " running from a camera man " contradict each other.
