Among the hodgepodge of signs that have sprouted in Zuccotti Park in Lower Manhattan, one man in jeans and a baseball cap has been carrying placards that shout their suggestions: “Google: Jewish Billionaires” and “Google: Zionists control Wall St.”

At the same time, among the sea of tarps under which protesters have been sleeping, a sukkah, a makeshift hut, was erected to celebrate the Jewish holiday of Sukkot.

The Occupy Wall Street protests, now in their second month, have increasingly been criticized by a variety of groups, most of them politically conservative, for flashes of anti-Semitism. Among those calling attention to the issue have been the Republican National Committee, Rush Limbaugh and the columnist William Kristol.

But the protests have also, on occasion, had a distinctly Jewish flavor: The encampment has coincided with the busy Jewish holiday season and has witnessed, in its midst or on its edges, a crowded Kol Nidre service on Yom Kippur, festive dancing with a scroll on Simhat Torah on Thursday night, and the sukkah.
