These two nonverbal cues can be seen in video footage of Adeel Khan, who today, was found guilty of deliberately setting the convenience store alight and murdering the man who lived upstairs. Khan pleaded not guilty to all charges. In this video, (at approx. 45 seconds) Khan's blink rate increases to 100 blinks per minute, in response to the question, "Mr Khan, I'll ask you, did you burn down the property?". There's a clear distinction between blink rate before and after the question.
