Lecture 2.2 a documentary on graffiti "Bomb It"

Today I watched a documentary on graffiti writing called "Bomb It". This documentary talked about between the people who love graffiti and who hate the graffiti in the world.  At the first of all, I don't know why they do graffiti in the street and everywhere.  Now I watched this documentary, I understand graffiti is the type of art. Graffiti writers want to express their feelings, Names, Social Words, etc. to the public, Graffiti represents positive things for the cities and they want people focused on this type of art. Graffiti is helped them to protect their life. Graffiti also help homeless people. They said homeless people can put their names to let people know who they are? Some positive graffiti writers posting to help poor people and let people to open their eyes, view reality, and do something about it. The people who against graffiti. They think graffiti is not a type of art. They believed these people don't protect the right to doing the graffiti in the street. They erased all the graffiti writing in the street because they think it is ugly in the street and they don't know what they doing. I think it is a good way to help poor people.
