NPR is reporting that the FBI and DHS did not issue a formal threat assessment ahead of the rally and riot last week.

Some security officials told NPR they were concerned that issuing a formal threat assessment would have First Amendment implications and a chilling effect on peaceful assembly. However, three law enforcement officials said DHS and FBI had issued full intelligence bulletins ahead of Black Lives Matter protests in Washington in June and ahead of the Islamic Society of North America’s annual convention.

This was despite the fact that the Norfolk FBI office had identified specific threats and people sharing maps of the tunnels beneath the Capitol. NYPD also alerted Capitol police and FBI last week, apparently.

I look forward to learning more.
