I love how the second part of Banksy's newest mural, which is a comment on censorship and oppression, was done by the very people he is critiquing.

Their response was predictable, and relied upon, and imho has created a masterpiece.

@ElleGray One assumes the artist put great thought into his materials, and what sort of after image would remain despite the best efforts to non-destructively remove the image. Non-destructive that is to the side of the building. Cuz that's what it's going to take to get rid of that image knocking out that whole section of limestone!
