From reader Don, who writes:

Saw this scrawled (spray-painted) on the underside of a bridge over the Trinity River, maybe 1.5 miles from the Occupy Dallas location. I stopped to safely take a picture. Star of David with “Zionist Occupied USA” …

I suspect (but can’t be certain) the Occupy Dallas crowd because of the proximity to the Occupy Dallas site downtown, the use of the “Occupy” terminology, and because this is painted on a bridge that one would pass on foot if crossing the Trinity River bridge to the Oak Cliff section of Dallas from the “Occupy” site in downtown.

I’ve been in Texas (Houston or Dallas) nearly 40 years, and I don’t remember seeing a single piece of “zionist” or anti-semitic-related graffiti, ever. I’ve heard of the rare vandalism attack on a synagogue or two over the years, but just general “public space” anti-semitic graffiti like this is rare to non-existent here. This is something new, and almost certainly related to the “Occupy” movement. An ill-wind…

It’s certainly possible, although referring to Zionist Occupied USA, or some variation, is a favorite slogan of neo-Nazis and White Supremacists.  Given the language we’ve seen from some elements in the Occupy Wall Street movement and the fact that the American Nazi party supports OWS, however, your instincts may be right.
