This reminds me of a thing I saw on TV about two bank robbers who were caught and couldn’t understand how the cops identified them. They told law enforcement officials that they were told that if they rubbed lemon juice on their faces, their faces would be blurred on the security cameras. Weird.
Does this work just as well on red light cameras?
Your story reminds me of something that happened on a church ski trip. The boys took a girls camera, dropped their pants, took pictures of their butts and returned the camera. when they got home, the girls had their film developed and SURPRIZE! Only problem the boys western belts had their names on them and they showed up clearly in the photos. busted!
