What is one of the key elements of Graffiti as defined under the law?

One of the key elements of graffiti, as defined under the law, revolves around the act of causing damage to property without the owner's consent. This aspect emphasizes that graffiti is typically considered a form of vandalism because it involves defacing or marking property that does not belong to the individual creating the graffiti. The lack of consent from the property owner is crucial; it highlights the unlawful nature of the act. In many jurisdictions, the law specifically categorizes graffiti as a criminal offense because it results in property damage and can affect community safety and aesthetics. Thus, when individuals create graffiti without permission, they are engaging in an illegal act that can lead to legal consequences.
