Final answer:
Walking to class backward best illustrates deviant behavior that is not criminal, as it defies social norms but does not violate any laws, unlike graffiti vandalism, burglary, assault, or embezzlement, which are also criminal acts.
Step-by-step explanation:
The example that best illustrates that deviant behavior is not necessarily criminal would be walking to class backward, which is deviant because it violates social norms but is not against the law, and thus not a crime. Deviant behavior refers to actions that go against social norms, while criminal behavior is the commission of acts that violate the law and are punishable by the state. Graffiti vandalism, burglary, assault, and embezzlement are all examples of criminal behavior because they involve the breaking of specific laws. Conversely, deviant behavior does not always result in legal repercussions, but rather social sanctions or disapproval.
