Eyal Wizman, Israeli architect and founder of the interdisciplinary research group Forensic Architecture, was informed last week by e-mail that his travel visa for the United States had been inexplicably revoked, as reported by New York Times. Weizam, who holds both a British and Israeli passport and claims to have traveled to the United States several times, went to the U.S. embassy in London the next day, but an official told him that an algorithm had identified a security threat related to him.
