Today we were in London, meeting some friends. On the way we crossed at traffic lights. As we did so a cyclist gently went through the red light, causing us no problem - but directly behind the cyclist was a police van. At first nothing happened, then Boo engaged the famous stare of power, first at the cyclist, then at the driver of said Police van. 5 seconds later, blue lights, cyclist pulled over.
A victory for the stare.
