WEST Berkshire Council left a piece of graffiti depicting male genitalia up for three months after officers deemed it not offensive enough to remove.
After making several pleas to the district council to clean up a defaced bus shelter on School Hill, in Chaddleworth, which had been daubed with vulgar artwork in March, Chaddleworth Parish Council this week received a written response from the district council which said: “Unfortunately, as it is not classed as 'offensive' it does not take priority and is removed by the Probation Service as and when they carry out work in the area.
“They have a significant amount of non offensive graffiti to remove in the district and it was unfortunate that they did not get out to your village to remove the small amount you have on the last couple of occasions they have worked in West Berkshire.”
The district council finally relented after repeated requests from the parish council, and sent a private contractor to paint over the scene yesterday (Wednesday) morning.
Spokesman for West Berkshire Council Keith Ulyatt said: “There is no sliding scale of what is deemed offensive and what is not, but something that is racially offensive or sexually offensive does get prioritised and removed immediately.
“The incident in question was not seen as offensive at the time and was not prioritised.”

What do you make of this?

Pictures fine but words not allowed?

Where do you draw the line (excuse the pun)?
