The FBI has over 1,000 active cases relating to possible terrorist activity. Of those, it is monitoring 48 Islamic State suspects that are considered so high risk it is tracking them with elite “mobile surveillance teams.”
“The FBI together with law enforcement agencies across the country are engaged in this” said Senator Dan Coats of the Select Committee on Intelligence told Fox News. “It takes enormous amount of manpower to do this on a 24-7 basis. It takes enormous amount of money to do this.”
Around a dozen agents are assigned to each case and conduct 24-hour surveillance on the target. The FBI monitors suspects it thinks are most likely to attempt a repeat of the Paris attacks on American soil.
The time between radicalization and the decision to carry out an attack can be extremely short, according to FBI Director James Comey.
“Together we are watching people of concern using all of our lawful tools” he said in a news conference last week. “We will keep watching them and if we see something we will work to disrupt it.”
Currently the FBI believes there is no credible threat to carry out a terrorist attack in the United States.
Attorney General Loretta Lynch and FBI Director James Comey give a briefing on the security measures to protect the United States from a terrorist attack.
