Answer:
I do believe graffiti should be illegal.
Step-by-step explanation:
The official definition of graffiti is, "writing or drawings scribbled, scratched, or sprayed illicitly on a wall or other surface in a public place". Meaning that graffiti is a form of vandalism. And because vandalism is illegal, I don't think any other forms of it should be considered 'ok'. That is my opinion on the subject. Note my 'opinion'.
