Two FBI agents came to the Henry Gallery at the University of Washington recently to ask curators about artist Steve Kurtz, the subject of a grand jury investigation into bioterrorism in Buffalo, N.Y. Kurtz had a show at the Henry. “I don’t know what I was expecting from the FBI, but they asked incredibly inflammatory questions. … I remember one of them asked, ‘If you heard there was an explosion in Buffalo that killed 100 people and Steve Kurtz was involved, would you be surprised?’ I said, ‘Yes, of course, there couldn’t be an explosion involving Steve. He’s an artist, not a terrorist.’ “
