The Department of Homeland Security (DHS) and its Immigration and Customs Enforcement (ICE) subsidiary are apparently on high alert to guard against a possible attack by anarchist terrorists in Chicago.

Two “law enforcement security bulletins,” ABC7 Chicago reported, say that an anarchist website has mapped ICE facilities in and around the city, and have even posted photos of ICE agents.

The alert comes days after leftist crackpots ambushed and attacked Border Patrol agents, federal authorities allege. Two weeks ago, a far-left crackpot attempted a mass murder at a facility in Dallas.

The two bulletins came from DHS and the Center for Internet Security. 

“The assessment from CIS said at least four Chicago-area ICE facilities, including Broadview, have been surveilled with detailed layouts, diagrams and photos posted to what is described as an anarchist website,” ABC7 reported:

Also found on the website reviewed by the ABC7 I-Team were photos of ICE agents, including names, faces and badge numbers.…

A separate Department of Homeland Security Joint Intelligence Bulletin from this month advises ICE facilities and personnel face an increased threat from domestic violent extremists similar to the two shootings at ICE facilities in Texas in September and July.

For months, far-left extremists, including Democratic elected officials, have interfered with and even assaulted ICE agents. But the danger is increasing, notably with the attempt to ambush Border Patrol agents. One of the suspects arrested, authorities allege, attempted to mow down an agent with her SUV. An agent fired at her five times.

“There has been an increase in the attempt to gather and, you know, anonymously, share and gather information online and publish it even on websites publicly available about these activities,” Jason Perry, a cybersecurity professor at Lewis University, told the station.

A consultant for the station noted, as did Chicago Police Superintendent Larry Snelling, that ICE agents are law enforcement and that it is illegal to impede them.

“These are law enforcement operations, and these are law enforcement officers that are doing what they were sworn to do, and you can’t interfere,” Bill Kushner told the station. “The more people resist this in a violent fashion, the more violence is going to be used to defend the officers.”

That was Snelling’s take in a news conference about the Chicago ambush.

“If you box them in with vehicles, it is reasonable for them to believe that they are being ambushed and that this could end in a deadly situation,” Snelling said, rhetorically asking why someone would follow law-enforcement agents:

What are you planning on doing?

It’s also reasonable for them to believe that you’re eventually going to do harm to them. If you ram any vehicle, especially that one that contains law enforcement agents, and that’s any law enforcement — local, state, federal, county — and you do this intentionally, this is considered deadly force. Deadly force is anything that can cause great bodily harm or death. When you plow into a vehicle that contains law enforcement agents, you’re using deadly force and they can use deadly force in response to stop you.

That’s what happened, again, when Marimar Martinez and Anthony Ian Santos Ruiz attacked the border agents on Saturday.

A federal criminal complaint alleges the pair cornered a Border Patrol vehicle. Then they rammed it. When an agent emerged from the vehicle, Martinez tried to run him down, the complaint alleges. The agent’s gunfire wounded her.

The pair are charged with resisting, assaulting, and impeding a federal agent.

In Texas, extremists have attacked two ICE facilities.

On September 24 in Dallas, far-left crackpot Joshua Jahn fired into the sally port of the ICE facility. He murdered an illegal alien and wounded two others.

Apropos of the anarchists who are mapping ICE facilities in Chicago, the attack raised serious questions about the culpability of ICE-tracking smartphone applications.

Jahn, who shot himself at the scene, used an app that tracked agents. He left behind notes that clearly showed his mission was terrorizing them.

Multiple defendants await trial for their role in a terror attack on the ICE detention center in Prairieland in July. Their attack was highly organized and involved military-style equipment such as body armor.

One of the suspects even carried a “Faraday Bag,” which is “used to block certain electromagnetic signals, including phone signals and are commonly used by criminal actors to try to prevent law enforcement from tracking location information through cell phones,” the criminal complaint says.

One of the leftists shot a cop in the neck.

In California in August, two employees at a healthcare facility were indicted for assaulting ICE agents who were attempting to arrest an illegal alien.

In Washington, D.C., the same month, a deranged former Justice Department employee hurled a sub sandwich at a Border Patrol agent and was charged with assault.

The escalating violence stems from the continued vilification of federal agents by top Democrats, who have repeatedly called them Nazis, the Gestapo, and terrorists.
