West Banksy.

The Guardian, reporting on Banksy's trip to the occupied territories, shows this poignant piece painted on the security barrier that separates Israel and Palestine. A statement from Banksy: "The Israeli government is building a wall surrounding the occupied Palestinian territories. It stands three times the height of the Berlin Wall and will eventually run for over 700km - the distance from London to Zurich. The wall is illegal under international law and essentially turns Palestine into the world's largest open prison... It also makes it the ultimate activity holiday destination for graffiti writers."

Update: Visual Resistance writes: "Man, just when Banksy had you feeling free, the New York Times has a report on the city’s new Citywide Vandals Task Force, the merger of the NYPD and transit cops’ anti-graffiti units started by Bloomberg’s crackdown on graffiti."
