SAN FRANCISCO — With anxiety heightened three months after terrorists struck a stadium amid a bloody series of attacks in and around Paris, local and federal law enforcement officials said Wednesday that there was no credible threat to Super Bowl 50 and that several measures, many of them not visible to the public, would protect it.
The secretary of Homeland Security, Jeh Johnson, flanked by nearly a dozen other law enforcement officials, said security for the game, set for Sunday, and for events surrounding it here this week involved an array of local and federal law enforcement agencies.
