I'll be back later to give my feedback, but quickly, I went back and watched the episode again. It was exactly as I remembered. When he broke the table trying to get his fingerprint, the policeman next to him says forget it, let's just get your mug shot, and they lead him off without getting his prints. After taking the mug shot, the police used the "mug shot" camera to take a bunch of pictures of themselves, all happy and smiling, posing with the man in blue. haha. So, no, no fingerprints of Superman.
