Graffiti or art?

We just got back from 2 weeks in Chile.  What a wonderful country Chile is.  Everyone seemed very happy and I was told by a local that Chile currently has the strongest economy for all of South America.  Don't know if that is true but the people on the streets were very happy.

Everyone has seen graffiti all over walls, garage doors or what not.  Chile is not immune from that either but the Chilean government passed some new laws that have had an impact.  The law basically classifies paintings on walls, garage doors, etc. as art.  Apparently there is different classes of offenses if you are caught putting graffiti on a blank wall or on top of art and if you do it on top of art the penalty is very steep.  This is what a local Chilean told me.  So what has happened is the emergence of art all over.  Here are some examples we saw so I ask you...graffiti or art?
