As a protest against the U.S. war in Iraq, Eric Wallach staged his own crucifixion at the Astor Pl. traffic triangle at Lafayette St. To crucify himself at the Wallach climbed on top of a crossing-signal sign and hung there about two hours. Passersby snapped cellphone photos of him near a altered one-way sign reading “No War.” When onlookers began to crowd the island, police moved them off and three officers took Wallach down, put him on a backboard and loaded him into a police vehicle. Wallach, who also goes by the moniker Radical Jew 33, is a freelance theater artist and self-described provocateur. “I just can’t stand the war,” he said.
