The FBI-Homeland Security intelligence bulletin that circulated midnight Tuesday is ominous, but entirely predictable, given widely published reports of far-right chatter over the past several weeks: It alerts local law enforcement officials that extremists may try to breach the U.S. Capitol Thursday and attack Democratic lawmakers.
The warning is based on a malevolent fantasy spread by followers of QAnon, the cultish pro-Trump movement—that Donald Trump will reemerge to take power as the rightful president on March 4, which was Inauguration Day until 1933. Preposterous, but the FBI has learned not to dismiss any threat, no matter how irrational.
“It does not take an armed takeover” by an organized group to do a lot of damage, says Tom O’Connor, an FBI agent who investigated suspected domestic terrorists for 23 years. “It takes one person who believes they need to act. How possible is that, I ask you?”
Dead easy, as the FBI knows from the many cases in which lone actors or a couple or three angry people unleashed spectacular destruction, including Oklahoma City bomber Timothy McVeigh, Olympic Park bomber Eric Rudolph, Unabomber Ted Kaczynski, Charleston church shooter Dylann Roof, and, most recently, Nashville bomber Tony Warner.
The FBI’s ability to surveil American citizens and build domestic terrorism dossiers on them is tightly restricted by laws and regulations enacted in the post-Watergate era.
That is why the FBI has developed alternative tools and techniques for finding and discouraging people who might be thinking of escalating from radical anti-government speech, which is protected by the First Amendment, to violent action, which is a crime.
FBI agents are currently deploying, among other strategies, preemptive interviews, also known as “knock and talk,” as a tactic for dealing with potential troublemakers when there’s insufficient evidence to file criminal charges—for instance, people who have been out bragging in bars or “shit-posting” online about their determination to come to Washington to help restore Trump to the White House, disrupt Congress or the Biden administration or intimidate lawmakers.
The knock-and-talk drill is powerful, requires no intrusive technology and no warrant. It goes like this: FBI agents, sometimes with local police partners, knock on doors of people of interest and ask to interview them. The mere appearance of courteous but unsmiling and obviously well-informed badge-carriers, armed with notebooks and a long list of very specific questions, is often enough to chill someone from carrying out a half-baked scheme.
“FBI agents and [Joint Terrorism] Task Force [police] officers routinely conduct these interviews with people who may have information or involvement in activity,” O’Connor told SpyTalk. “The effort is to let the interviewee know the FBI is aware they have potential involvement or information. This may slow the person’s potential involvement and most importantly, after building a relationship with the person, may produce information which will stop potential violence.”
“These interviews are related to [uncovering] potential criminal violence,” he stressed, “and not First Amendment-protected activity. The FBI in no way is looking to chill a citizen’s rights to peaceful protest or free speech.”
On Wednesday morning, Jill Sanborn, the FBI’s assistant director for counterterrorism, alluded to the FBI uses of the knock-and-talk technique to deter known violent extremists from traveling to the Capitol for the January 6 event. Testifying before a joint session of the Senate Homeland Security and Rules committees, Sanborn explained that of the 257 people charged so far for taking part in the riot, only one person was already under criminal investigation for domestic terrorism-related activities. Asked why so few documented domestic terrorists were in the crowd, Sanborn replied, “We were aware of some of our subjects that intended to come here. We took overt action by going and talking to them to get them to not come. That worked in the majority of our already predicated cases.”
FBI director Christopher Wray made a similar disclosure to the Senate Judiciary Committee on Monday. “There were individuals on whom we had previously predicated investigations, that we saw getting ready to travel,” Wray said. “…We had agents…approach those individuals, interview them, and even if we didn’t have the basis to charge somebody, it persuaded a number of those people from traveling.”
Wray said the FBI has 2,000 open domestic terrorism investigations, a fourfold increase over 2017.
Knock-and-talk is “not new and certainly not just for terrorism,” says a retired agent with extensive experience in domestic and foreign counterterrorism investigations. “It’s been done for years on organized crime cases. Sometimes to keep people from possibly doing something and sometimes to shake the bushes and see what reaction you get. Put pressure on a group of people, make them worried, make them suspicious and see what they do. In some cases where you are employing [court approved] Title III judicial wiretaps, you do interviews to see who the guys you talked to call. Do they call their bosses, or do they warn people? It’s a great technique. It works on different levels and it sends the message, ‘We are watching you. We know who you are.’ People think the internet makes them invisible. Sometimes they need to be reminded that’s not true.”
Last week, acting Capitol Police Chief Yogananda Pittman disclosed another malign fantasy reported by a FBI-Homeland Security intelligence bulletin—that some domestic extremists were talking of bombing the U.S. Capitol while President Biden was addressing a joint session of Congress in a State of the Union-style event, to assassinate the President and his cabinet and kill every lawmaker in sight.
“The State of the Union is the juiciest target this country ever had, but the logistics are challenging,” says a retired senior FBI counterterrorism agent.
“We always took the attitude, if your purpose is to stop the State of the Union, all you have to do is set off a bomb somewhere in D.C. and that will shut everything down,” he said, speaking with SpyTalk on condition of anonymity. “If a car bomb goes off in front of Union Station,” four blocks from the Capitol building, “they’ll stop it.”
Presumably, the Secret Service would whisk the president away to a bunker and congressional leaders would also go to ground.
But, the ex-G-man adds, “If your mission is to blow up the whole Capitol and decapitate the government, you better use a cruise missile because that’s the only way you’re going to get it.”
As during previous State of the Union events, when the president travels to the Hill, streets around the Capitol building will be closed. Many are already closed off from the January 6 riot. Some will be blocked with buses and trucks. Secret Service, FBI, Homeland Security and local law enforcement surveillance teams will be everywhere, in patrol cars and on foot.
Choppers and Sniffers
Counter terror veterans say that military aircraft, customs, and police helicopters will overfly the Capitol and nearby streets, looking for everything from light aircraft to armed drones. Radiation detectors will be mounted in aircraft, cars and in backpacks shouldered by plainclothes agents, so they can head off “dirty” bombs packed with radioactive trash as shrapnel.
The Capitol Police force has the biggest bomb squad in Washington, D.C., the ex-G-man says, and if its bomb techs encounter a device they can’t defuse, they’ll be able to summon backup from the FBI’s Hostage Rescue Team, which includes specialists trained to render safe unusual explosive devices.
“If somebody wanted to put a package bomb on a drone, it would be hard to catch, hard to stop, but it wouldn’t do much damage,” he says. “If somebody wants to put a plane down somewhere, it’s very hard to stop that.”
“It is possible [to hit the Capitol building] with an improvised missile,” Dave Williams, a retired FBI bomb tech who now consults on security, told SpyTalk. “The payload would be limited depending on the delivery system, but 20 pounds of high explosive would get some attention. A drone attack is unlikely, due to electronic jamming systems that could/will be in place. But a homemade rocket/missile has been made by a number of people. And they could easily fire it from a good distance away, a mile or so. It’s not out of the question.”
That’s a chilling scenario, because the domestic extremist movement has attracted a significant number of military veterans. Some of them, or some to be recruited in coming months, could have useful artillery skills. Any explosion would yield the kind of publicity terrorists crave.
Nightmares of Bombings Past
A truck bomb would be a terrorist’s preferred, low-tech method for demolishing part of a massive stone building. The bomb that blew up about a third of the Oklahoma City federal building on April 19, 1995, killing 168 people, consisted of about 4,000 pounds of ANFO—ammonium nitrate fertilizer mixed with fuel oil—concealed in a Ryder moving truck. Williams says it would take at least that much ANFO or another homemade explosive to wreak equivalent damage on the hallowed Capitol building. A car, pickup or van couldn’t hold that much. Large trucks are impossible to hide, and they’re under routine scrutiny in Washington, especially during special events.
A smaller amount of stolen military high explosives such as C4, PETN or TNT might do the job, but Williams doubts a terror group could get its hands on enough to create a catastrophic event in Washington.
The most diabolical scenario is an explosion, or a series of them, detonated by an insider—or an outsider who has gained access to the building.
The pros say that’s been considered. They say that since the anthrax attacks in 2001, the Capitol complex’s air conditioning system has been outfitted with filters that capture particles down to nanograms. These filters are regularly checked with forensic instruments that can detect particles of chemical explosives and also biological and radiological agents.
As well, the Capitol Police make regular rounds with dogs trained to sniff explosives. Dog’s noses are often more sensitive than machines, and they like the job.
“It’s like play for these dogs,” says Williams.
“They have all kinds of detectors within the Capitol, with all kinds of different levels of sensors,” says the ex-G-man. “The military has mobile systems that you can run out of a Humvee to detect explosives. They’re designed to protect troops out in the field. They work in fields, jungle, deserts.” So, the thinking goes, they’ll work well on Capitol Hill.
“At this point, all threats have to be run to ground,” says O’Connor, who retired from the FBI in 2019. “The threat does not have to be fully vetted and confirmed to have actions taken to guard against potential attacks. The threats of overrunning the Capitol were thought by many to be along the same lines. No agencies will be writing off any threats until they are proven non-credible.”
Privately, though, some FBI counter-terror hands expect the attack-the-Capitol moment to go sideways.
“Guys like this don’t want to go toe-to-toe with security forces and police that they know are waiting for them and really, really want another shot at the rioters,” says a retired FBI agent. “The Capitol Police and the National Guard both want to prove to the world that they can do the job and would love for people to try and breach the Capitol again. I expect lots of online rhetoric. I expect several groups to declare Trump is president again. I expect stories of a ‘secret Inauguration’ taking place.”
Nothing for a while. Then maybe a change of venue.
“If I was Capitol Police,” says the ex-G-man, “I would be more concerned about direct actions taken against specific congressional leaders when they are at home or traveling back to their home offices. That is when they are most vulnerable now.”
Responding to the threat of violence, House leaders cancelled Thursday’s session.
