Each time a diamond is stolen, a red beam is seen over it. In one instance, LaBond sets up balloons to emit "decoy" red beams while the real one steals the diamonds. As it is obvious as to what the real beam does, no explanation is ever provided for the "decoy" ones.
At the circus, while a diamond is being stolen, Superman shows up to try to stop it. During this time, two elephants and on gorilla escape, yet Superman offers no help with containing them.
