Which of the following is not classified as a crime against property?

Assault is not classified as a crime against property because it specifically pertains to the violation of a person’s physical integrity and safety rather than their belongings. Crimes against property typically involve actions that directly harm or invade someone’s possession, such as theft, mischief, or break and enter. Theft involves taking someone else's property without permission, mischief includes damaging or interfering with property, and break and enter refers to illegally entering a building with intent to commit a crime therein. Therefore, assault is distinctly categorized under personal crimes, making it the correct answer in this context.
