You completely missed the point of the example insofar that the Bill accepted that Graffiti is already defined and pursuant to the criminal damage act 1971. (one of the reasons it did not pass)
If there was no consent then a criminal offence has taken place. That is it, there is no alternative position just because the graffiti is good...Clacton Council removed the Banksy Graffiti therefore an offence was committed as defined under the legislation available...it would be up to the CPS to decide any action if Banksy was caught, not The Council. If no prior consent was given then an offence has been committed. (for example, say Banksy was in the process of spraying one of his stencils when he was arrested..do you think the council can tell the Police or CPS to release him because of who he is?..the answer is no they cannot...unless they can show they gave prior consent to paint on that wall/building then the police will charge him with an offence) This is why Clacton offered to allow a more appropriate arrangement..i.e a legal one.
You are wrong, without consent it is vandalism...but if you are so sure you are right then nothing I can say with alter that.
It really can't be criminal if the graffiti is welcome.
Clacton, yes, that could constitute vandalism - there was damage which the council had to rectify.
But, where a Banksy is welcomed, as it often is, it isn't a crime - the crime is not in the act of graffitiing itself, but in the damage (if you're arguing vandalism which is where this all started), and it simply can't be legally considered damage because it is considered an improvement by the owner.
