According to my own, now graffiti more towards to street art that frees bomber / writer expresses his work through the lines and form a certain pattern in the added composition of attractive colors and typically use the initials of his name or his crew.
But today, graffiti has been regarded as art.
Basically, vandalism refers to the destruction of the property of others as well as the goods intended for the public interest. But vandalism also has aspects of emotion in doing it. Furious and annoyed or even just to release the sheer boredom, usually the reason for vandalism. Clearly, when damaging the public interest with an emotional charge as a motivation, then we can say that part of the form of vandalism.
But also many people who see graffiti is a form of artistic expression, which is much better than the walls filled with commercial messages. And once again, the graffiti also should be appreciated as works of art.
Graffiti until whenever maybe is going to be controversial. On the one hand it will say that graffiti is vandalism behavior, but the other hand interpret graffiti as art and freedom of expression.
