I kind of like graffiti street art. Graffiti as in a mixture of visual expression, street art, talent, juvenile delinquency and misdemeanor.
Taggers, bombers, writers, whatever they call themselves, they all show audacity, creativity, skills and misconduct because:
"If it is not authorized by the owner of the structure or building it is made on, graffiti is punishable by law, just like vandalism or misdemeanor. There are several possible legal consequences if you get caught making graffiti. You can be taken to court and sentenced to jail or incur a fine."
