Street lights<br>Ben lived on a dark street. There was an increase of car break-ins in his neighborhood. Ben started a petition to get street lights for his street. After the lights were placed, crime on his street dropped. The neighbors were glad that Ben started the petition.
Crime didn't drop until some time after the petition.
Actually, after the petition got the lights, crime on his street dropped, so the statement is true. Maybe the negative statement fooled the model.
