Yeah, one of my distant friends is a councillor in a borough where Banksy did a mural years back and it was definitely much more about ensuring the standing "Send in workers to paint over any graffiti" reaction doesn't happen than some sort of "That's nice, the committee which issued the permit for this didn't tell me when it would happen". So far as she told me she heard about it the same way most people did, it was on the local news that morning.
