You are the prosecuting attorney in a case. You are eliciting testimony from your star witness, who has said that he was sitting on his porch 600 ft away from the crime scene when he saw the defendant commit the crime in broad daylight. You ask, How did you know that it was the defendant?" Reply: "I recognized the Angels baseball cap the defendant often wears, the same cap the defendant is wearing now."

Question:

"How did you know that it was this Angels cap and not an ordinary cap of the same color?" Reply: "I could see the big A very clearly."

Question:

"You are absolutely sure of this?" Reply: "Yes, absolutely" With sudden shock you realize that your star witness is lying. How do you know this?
