It is one of the most basic of instincts people develop as children -- to flee when facing potential trouble. Often, when a parent discovers a child holding a forbidden item, the immediate response from the child is to drop the object and run away as if the lack of his presence would indicate he was never there. These practices often follow through into adulthood. Sometimes, when an adult finds himself in a situation that could get him into trouble, the natural response is to leave the scene and hope no one knows he was there. That is what police claim a New Jersey man did last week after he was involved in a drunk driving crash.
