I’ve included the entire NY Times article ( FBI Pushing to Stop Domestic Terrorists, Grapples With Limits on Its Power) below. I have noted several times in the past the refusal of the FBI or any other federal agency to keep track of and publish annually statistics on domestic terror attacks. This article has stats on 2018 and 2017 which are of interest but there needs to be more than just the last two years to understand the threat and to allocate resources to it. The article also makes the point that the Bureau needs new federal statutes to better address domestic terror attacks. Hopefully they will get what they need as domestic terrorism has become a bigger threat that international inspired attack in the US over the last half dozen years.
