I did read the article and because he had a direct role in the destruction thats all the more reason not to deface it. Its a reason to hang it in a gallery with a little plaque explaining what he did then when people see that artwork and read the plaque they will understand maybe they didnt understand before maybe this is news to them maybe they are learning and forming a more informed opinion maybe it will inspire them to do something. Or we can deface it remove it hide it away and that discussion about what he did why he did it will be lost forever.
