In fortified Washington, residents wonder whether Capitol riot was a one-off or omen of worse to come

• Follow live inauguration coverage

In a moment of nation-splintering turmoil, an incoming American president, Abraham Lincoln, travelled by train to his inauguration inWashington, D.C., in a nerve-racking ride cloaked in disguise as he faced threats to his life.

Now, 160 years later, anincoming president has cancelled plans for a train ride to Washington.

It was supposed to be a symbolic journey highlighting Joe Biden's decades-long habit of riding the rails to D.C. each day fromhis family home in Delaware.

Instead, it hastaken on a sadnew symbolism, of an American capital clenched shut in fear of political violence at Wednesday's inauguration.

The question nagging at residents here, and at security analysts, is whether the Jan. 6 attack on the U.S. Capitol was the worst of a passing storm, a one-off, or the start of a dark era of political violence.

What's already clear isthis will be no normal inauguration. The American capital has transformed into a heavily armed and tightly barricaded fortress.

"Clearly, we are in uncharted waters," Washington Mayor Muriel Bowsertolda newsconference last week, urging tourists to stay away from her city during the inauguration.

Fences are now up around Washington's downtown. Thousands of soldiers are patrolling the streets, bridges are blocked, parking garages are shut, bicycle-sharing services are suspended, Airbnbreservations are cancelled, and residents are being urged on neighbourhood chat groups against renting rooms to tourists.

Suspicion strikes CapitolHillneighbourhood

Security concerns are most acute in the neighbourhood near the Capitol.

Lawyer Matt Scarlato already has an overnight bag packed in case unrest spills into his neighbourhood and he's forced to flee the city with his family.

He lives near one of the new security barriers near Capitol Hill, where police are forcing residents on some streets to show ID if they want to access their home.

Scarlato was working from home the day of the riot in the Capitol building, when unexploded bombs were found near political party offices.

He received a message from his son's daycare urging parents to immediately come pick up their children.

Scarlato grabbed a baseball bat and tossed it in the car for the ride to the daycare.

"It was a minute-by-minute escalation," Scarlato said. "We were all just sitting in the house saying, 'What the hell is going on?'"

A longtime resident of the area, he comparedthe recent panic to a smaller-scale version of what he witnessed during the attacks ofSept. 11, 2001.

On the day of the Capitol riot, he was concernedby the sight of an unfamiliar RV on his street given the reports of bombs in Washington and the recent explosion in Nashville.

For her part, Monica Ingram,a retired health-care administrator,was rattled yesterdaymorning by the sound of helicopters hovering over the same Capitol Hill neighbourhood.

Around that same time, the congressional precinct was ordered evacuated. The panic was the result ofan explosion and fire nearby, caused by a propane tank in a homeless encampment.

Ingram said people now look at each other differently, warily. Ingram saw a man taking pictures of streets near the Capitol the other day and she worried whether he was up to something nefarious.

"We're suspicious of each other now. It's sad," she said. "It's very disheartening, upsetting. It's like I don't even know this country anymore."

Tensions high in Washington ahead of inauguration

4 years ago

Security is tight and tensions are high in Washington, as the U.S. prepares to swear in Joe Biden on Wednesday. Thousands of National Guard troops brought in to protect against possible attacks are being vetted by the FBI for possible inside threats.

Some call for indoorinauguration

She's among the many people with mixed feelings about whether today'sinauguration should even be happening in public.

Ultimately, she prefers it going forward, as opposed to moving to a makeshift indoor location, in order to deliver a message: that this country won't buckle in fear.

There is, however, a part of her that hopes Biden might throw another inaugural party, a year from now, a real festive party, after this pandemic, and this panic.

Biden should have a "redo" inauguration,shesaid.

"It's so sad that president-elect Biden has to be sworn in like this. It should be a day of joy for this country."

There's no guarantee this place will feel safer in a year.

Mark Hertling, a retired lieutenant-general who led U.S. soldiers in Europe,said he worries about whether the United States is now entering an era of political insurgency.

And he's not alone.

One-time riot or previewof insurgency?

Some analysts who study domestic political violence have warned for years (in thesis papers and books and government reports) that the conditions existed for an American insurgency on the right.

Those conditions include a proliferation of guns, a surge in ex-military joining militia groups, two increasingly hostile political parties, and a split along racial and cultural lines in a rapidly diversifying country.

A 2018 book, Alt-America, charts how membership in armed militia groups skyrocketed after the election of a first Black president, Barack Obama, in 2008, and these fringe groups began showing up at political protests.

Alleged members of such militias are now accused of participating in the Jan. 6 attack on the Capitol, where numerous people were dressed in paramilitary-themed clothing and several could be heard in the crowd warning they'd be back with weapons.

"Welcome to the reality of other countries," said Greg Ehrie, who led FBI domestic terrorism units andis now vice-president of law enforcement and analysis at theAnti-Defamation League.

"There is sort of an underlying belief that if we can get through Wednesday, this stops and then it moves on. And that's just not true. This is going to be something we're going to be living with for several years this heightened sense of security."

Details released since the siege of the Capitolsuggest things could have been worse.

Jan. 6 could have been worse

One man arrested that day allegedly had two guns and enough materials to make 11 Molotov cocktails, andanother allegedly had a loaded gun, spare bullets and a gas mask.

A federal prosecutor said one air force veteran who carried plastic handcuffs intended to take hostages.

Rep. Alexandria Ocasio-Cortezof New York City said in a YouTube video she believed she was going to die during the riot in the Capitol andthat she experienced a traumatic event she declined to discuss: "Many, many, many members of Congress were almost murdered," she said in the video. "We were very lucky [to escape]."

One police officer died as a result of injuries sustained during the riot. Another said he narrowly survived the angry mob and described how he was Tasered while some wanted to take his gun and kill him with it.

Joseph Young, a professor at American University in D.C. who studies the factors that drive political violence, usually in other countries,said he is bothered by the trends he sees.

"More and more, my work has been applicable to the United States," he said in an interview. "[And that's] troubling."

A word of historical caution

He said it's wrong, however, to conclude this is a more violent political era than the 1960s and 1970s. The U.S. experienced hundreds of terrorist attacks back then, from white-supremacist church bombingsto political assassinations to the activities of the left-wing group Weather Underground, which bombed the Capitol, the State Department and other government buildings.

But he's still worried about the current U.S. situation. As are the authorities preparing for today'sinauguration.

The Pentagon has authorized the Washington, D.C., National Guard to carry weapons on domestic soilamid ongoing worries about thepossible use of explosives. About 25,000 National Guard troops from D.C. and several states were expected to be part of the security operation.

National Guard members are being screened themselves for any extremist affiliations. On Tuesday, Pentagon officials said 12 National Guard members were removed from securing Biden's inauguration after vetting by the FBI, including two who posted and texted extremist views about Wednesday's event.

ASecret Service member was reportedly under investigation over political comments related to the Capitol riot posted on Facebook.

Jared Holt, an expert who monitors extremist chatter online, saidit hasgotten quieter lately.

He said he was extremely worried before Jan. 6 about the heated and violent rhetoric he saw in online platforms.

People were posting tips for smuggling guns into Washington and maps of the underground tunnels connecting the Capitol to lawmakers' offices.

Those same forums erupted in joy after the attack.

"It was initially jubilation," said Holt, of the Digital Forensic Research Lab at the Washington-based Atlantic Council think-tank. "They were thrilled. They felt incredibly accomplished. [Now], the cohesion between groups has eroded."

It became clear within hours of the riotthat it might backfire against those involvedand against Donald Trump.

It failed to stopthe vote to certify Biden's election win.Then it led to Trump's swift impeachment in the House.

Washington's streets fortified ahead of Biden, Harris inauguration

4 years ago

Duration 2:45

With the inauguration of Joe Biden and Kamala Harris fast approaching, U.S. authorities have gone to great lengths to ensure a safe transfer of power and to prevent violent riots similar to what happened on Jan. 6. Tens of thousands of National Guard troops have fortified Washington, D.C., and imposed tough restrictions on movement that give the U.S. capital an air of occupation.

Has the threat already receded?

Some rioters in the Capitol who posted triumphant images of themselveson social media have been arrested or fired from their jobs, with their posts used as evidence against them.

Social media platforms are either limiting extremist rhetoric and shutting out Trump, are offline altogether(Parler), or are unusually slow (Gab).

Holt now worries that violent rhetoric is moving to tighter channels that are harder to monitor publicly, such as Telegram and other private messaging apps.

So residents of Washington, D.C., and the country as a whole, enter this historic transition week in a fog of uncertainty, about whether they've just witnessed a dark passing moment in the life of the American republicor a sombre omen.

"It looks like a police state down here. We've never seen it like this," Emilie Frank, a communications professional, said in an interview a few days ago, referring tothe imposing concrete-and-metal labyrinth being erected downtown.

"It would normally be bustling, everybody's excited [for the inauguration]. But it's silent, blocked off, police cars everywhere."

She doesn't know if any of this will be necessary. But she'd rather have this than the under-preparation by authorities that the city witnessed on Jan. 6, she said.

"So, even if it's just [for] show, it's better than nothing, I guess," she said. "If some people will be convinced they should stay away after seeing all this stuff in place, then that's good."
