The FBI is carrying out ongoing terrorism investigations in all 50 US States, said its director, James Comey.
Comey spoke in Utah at a news conference about the FBI's efforts to tackle the Islamic State’s highly successful online propaganda.
"It's a message that goes to troubled souls anywhere in the United States. As a result, we have investigations in every state in the Union that focuses on trying to understand who is consuming that poison,” he said.
He noted the conflict between security needs and online privacy, saying: “Those values are increasingly in conflict when lawful court orders in criminal investigations encounter unbreakable encryption and we need to figure out a way as a people how to accommodate both of those values.”
He called on the public to report anything suspicious to the authorities, no matter how seemingly minor.
Law enforcement has been successful in stopping “over 60” Islamic State plots so far this year, according to the chair of the House Homeland Security Committee Michael McCaul.
He made the remarks highlighting the successes of the security forces in the aftermath of the Chattanooga shooting on July 16, in which four marines and a naval sailor were killed.
