Bobby lives with his parents in London. Last week, while his parents were out, Bobby's neighbour Susie came round to spend the evening. At 8 o'clock precisely she went out to buy some cigarettes from the corner shop 5 minutes walk away. One minute after she left, two men burst into the house and, ignoring Bobby, took the TV set, the stereo and a computer. Bobby had never seen the men before and they had no legal right to remove the equipment - yet he did nothing to stop them. In fact, he didn't even act surprised by their behavior. 

Why not?
