Ok I figured it out but, I don't know about it being so funny. If the police officer is visually impaired he probably uses a tape recorder ( I had a boss who was blind and he took notes on a hand held computer of sorts) and is more sensitive to verbal sounds and could pick up on if the blonde lady was not telling all the facts. I bet another officer was locking up the squad car and he/she would do the finger printing.

Thanks for another great doggie story.
