If ever proof were needed that the world has gone mad then this is the photographic evidence. It is of a defaced Banksy close to Exmouth Market. It originally showed a girl being lifted up by a robot arm, extending from a cash machine. Somebody decided to ruin the piece with a paint roller before someone else took the decision to preserve it with a protective perspex screen. The end result is that an act of vandalism has been sabotaged yet preserved for posterity.
