Vandalism

The beautiful David Choe & DVS1 piece by St.Petri church in Stavanger has been destroyed as the caretaker was washing the wall with a high-pressure cleaner.

I have no idea why the management got the idea of cleaning this wall, just see how it turned out:

Now who are the vandals now? The street artist or the property owner?

Will the Logan Hicks piece few meters down the same wall be ruined in the same way?
