Secure Ideas

I was thinking about using graffiti as the backbone of this project. There is a big uproar about graffiti inciting worse crimes. Case in point: I heard a rumour recently about a hip hop shop in the city being shut down under the new sedition laws. The issue was that they were selling graffiti magazines which 'obviously' cause people to break the law. These laws were passed to protect Australians, to ensure our ongoing security, and sure graffiti can be illegal, but it also can be legal and commissioned.
I am trying to come up with a novel idea with which to attack this problem.
The issue is that mostly graffiti isnt really my style, and heaps more research is necessary. Just an idea.
