The 2015 Muhammad Art Exhibit and Cartoon Contest, organized by the American Freedom Defense Initiative and held at the Curtis Culwell Center in Garland, Texas, featured a contest for cartoons of the Islamic prophet Muhammad. The event was attacked by two gunmen, Elton Simpson and Nadir Soofi, resulting in injuries to security officer Bruce Joiner. A subsequent civil lawsuit filed by Joiner alleged FBI negligence, citing an undercover agent's communications with the attackers—including encouragement like 'tear up Texas'—and failure to prevent the attack despite prior knowledge. The suit raised concerns over FBI counterterrorism tactics and potential entrapment but was dismissed on sovereign immunity grounds, with the dismissal affirmed on appeal.
