Graffiti is not a victimless crime or a harmless prank. It is a form of vandalism that encourages littering, loitering, crime, violence, and more graffiti.
Graffiti vandals "tag" or put their moniker or nickname "up" in multiple locations for fame and/or social rebellion. Gangs and drug dealers mark territory with graffiti. Some graffiti may be artistic, however, it is done without permission of the property owner and is therefore, a crime. Publicity encourages more graffiti.
The best way to fight graffiti is to remove it. Call the Hotline. The Allentown Graffiti Busters program removes or covers the graffiti (depending on the surface of the structure) at no charge to Allentown property owners.
