Detective Miller walked into a dimly lit diner where a man sat alone, claiming he had just witnessed a hit-and-run outside in the pitch-black alley at 3:00 AM. The streetlights had been broken for weeks. Miller asked the man to read the small print on the ketchup bottle, and then arrested him for filing a false report. Why?
Night blindness
If the alley was in pitch-black darkness and the streetlights were broken, the witness couldn't possibly have seen a hit-and-run without night-vision equipment. His ability to instantly read the fine print in the dim diner proved his eyes weren't adjusted to deep darkness.
