Or they are safeguarding their freedom to express themselves.
Pity. Many of them deserve to be recognised rather than plagiarised.
"I laugh at the way some people think graffiti is all selfish tagging and vandalism. Thoughtful street art is like good fiction – it speaks out on behalf of everyone, for us all to see." - Carla H. Krueger
