A common fear among Americans is that the Nov. 3 contest between President Donald Trump and Democratic challenger Joe Biden remains undecided and may lead to protests that could escalate into civil unrest or even sectarian conflict.

However, some Americans worried about possible violence after the U.S. presidential election are purchasing guns, forming community watch groups and others are working on conflict de-escalation, according to two dozen voters, online groups and data surveyed by Reuters.

An illustration of those concerns came in Michigan on Thursday, with the announcement that 13 people had been arrested in alleged plots to kidnap the state’s governor and attack the state capitol building.

For Americans like financial adviser David Powell, the greatest worry is that they could be forced to take sides to protect civil rights, private property, and even lives.

“I’m not part of any group, don’t want to be part of a group, I’m your regular guy who is watching the news and is getting really concerned,” said Powell, 64, of Raleigh, North Carolina. He said he worries about “antifa thugs,” a term U.S. conservatives use to describe left-wing anti-fascist activists. He said he is prepared to “stand guard” in his community, if necessary.

Some people are planning foreign vacations around Election Day or heading to rural retreats. Others have bought guns for defense.

Firearm sales hit a monthly record of 3.9 million in June, according to FBI data. Ammunition for AR-15-style rifles is on backorder in states like Washington and Colorado.

“I bought an AK-47,” said a Denver-based lawyer who identified himself as Ewing, and asked that his full name not be used. “The ammo is inexpensive and I can still get it.”

Some communities and groups are trying to deescalate tensions, often with the knowledge that many people have firearms and are prepared to use them.

In Portland, Oregon, left-wing activist Dre Miller has reached out to leaders of the right-wing Proud Boys to set up an open line of communication to resolve conflicts.

“We need to be able to call a cease-fire when things get out of hand,” said Miller, 37, an organizer with black rights group J.U.I.C.E. “As a black man I cannot stand back right now. I’m standing up and standing by,” echoing words Trump used about the Proud Boys.

The primary “terrorist threat” facing the United States, according to an Oct. 6 Department of Homeland Security report, are lone offenders and small domestic extremist cells who may act out grievances.

An October poll by political scientists including Lee Drutman of the New America think tank published in Politico found around a third of Americans justified violence to advance political goals, double the number in December 2019.

“The most likely outcome is the election happens, there’s no major violence, but the risk of serious or even low-level violence is probably higher than it’s been in a very long time,” said Drutman.

 down 6,500 pages and groups over the next month, but less explicitly militarized communities of hundreds of thousands of people remain online.

“That’s what is galvanizing and driving militia groups and other armed individuals to think that they have a role to play in this moment of sweeping social change,” said Joan Donovan, a misinformation expert at Harvard.
