Christian G. Martin V. - Is Graffiti Vandalism or Art?

Some may say that graffiti is unauthorized markings, while others say it's a beautiful form of art. This topic has been a controversy for many years which is that people view graffiti as an illegal activity, but also view it as a form of expression. This issue still remains unanswered to this day. People say graffiti art is a way to express one's emotions, but some say it's tagging properties. Whether its art or vandalism, the answer is up to you. What do you think?
