In 1996 a short, fat man robbed two Pittsburgh banks with no disguise in broad daylight. A local news station showed security tapes resulting in a tip which led to the man's arrest. An odd sort of urban myth led to the (rather ignorant) criminal's capture. Why did the criminal think he was invisible?
When McArthur Wheeler was arrested, he muttered "But I wore the juice, …". Apparently, he was under the deeply misguided impression that rubbing one’s face with lemon juice rendered it invisible to video cameras. Source: http://opinionator.blogs.nytimes.com/2010/06/20/the-anosognosics-dilemma-1/
