Crime scene getaway

In some jurisdictions, the very act of making a getaway from a crime scene is an inchoate criminal offense in itself, though it is generally viewed as natural behavior for a lawbreaker. For example, under New York law, ``escape'' is defined as escaping custody or detention; ``unlawful fleeing a police in a motor vehicle'' is a distinct crime.
