If a person is considering using gasoline and matches to damage someone else's property, what type of crime would that be categorized as?

A person considering using gasoline and matches to damage someone else's property would be committing arson. Arson is defined as the intentional and unlawful act of setting fire to or exploding a building or personal property. The use of gasoline as an accelerant implies a deliberate act to cause fire, which is a key element in the definition of arson.

While vandalism involves the intentional destruction of property, which might also occur in this scenario, the method described—using fire—clearly elevates the act to arson due to the potential for serious harm and the use of dangerous substances. Thus, the correct categorization of this potential crime is arson.
