People work hard to acquire the property they have. Most people want their property to remain in good condition for as long as possible. Sometimes, other people will take it upon themselves to destroy or deface property that belongs to another person. This might be done for any number of reasons, including trying to show off their artistic abilities in the form of graffiti. No matter what the reason, defacing or destroying another person's property is a criminal act that can lead to criminal charges.
Some people might not realize that even actions that seem more like pranks, such as egging a home, are considered vandalism. Other possible acts of vandalism include keying a car, slashing tires, breaking windows, knocking down signs, altering street signs or spray painting someone else's property.
