The Writing on the Wall department

According to today’s Jerusalem Post, a young man was arrested in Jerusalem for spray-painting “pro-Olmert” graffiti. Apparently he sprayed the message “Olmert will not divide Jerusalem” on a wall of the Malha shopping mall.

…All of which would be moderately interesting, if only because the people who spray-paint stuff on walls usually have rather more exciting (or, at least, rather more vivid) messages to convey; but there’s one thing about the story that I find truly strange: Who exactly decided that “Olmert will not divide Jerusalem” constitutes pro-Olmert graffiti?
