A WARNING – AT 11:27 A.M. ET:  It's sad that warnings like this have to be issued on Christmas Eve, but that's the world we have.  From CBS local: 

WASHINGTON (CBS) — Federal authorities warned Friday that Islamic State of Iraq and Syria sympathizers “continue aspirational calls for attacks on holiday gatherings, including targeting churches.”

The bulletin was issued by the FBI and Department of Homeland Security and issued to law enforcement agencies and private security companies around the U.S.

There are no known specific, credible threats, U.S. law enforcement officials say. The bulletin was issued out of an abundance of caution given the public nature of the posted threats and the holiday season.

The bulletin was sent Friday to law enforcement after pro-ISIS websites had published a publicly-available list of churches in the United States.

The bulletin also describes the different signs of suspicious activity law enforcement should be aware of.

In the past, public threats by ISIS supporters have focused on military and law enforcement targets. The more recent threats have expanded to include the type of attacks we saw in Berlin, Nice, France, and Columbus, Ohio.

COMMENT:  I would take these warnings seriously.  In Europe and Australia some serious holiday plots have been broken up.  We are very vulnerable here during a presidential transition, and the current president is on another of his extended Hawaiian vacations, presumably resting up for the resting up that will follow January 20th. 

Eternal vigilance.
