"This is no longer theory about what could happen," Pierre Thomas, ABC News Chief Justice Correspondent, told ABC11. "They've seen it happen. As a consequence they know there are people like that from across the country and they're treating it as such."
Gov. Cooper deployed around 350 Guard personnel to duty in North Carolina this weekend to "support state and local authorities and protect the well-being of residents, property, and the right to peacefully assemble and protest."
"The bureau and FBI Director Christopher Wray has been very specific," Thomas explained. "They understand free speech, they understand Americans can take positions of all manner. Some of them, even extreme points of view. What they're looking for are people talking about hurting other people and that's when the FBI can and will get involved. Various dark side chat rooms, social media sites have been encouraging people to go to State Capitols to register their anger and frustration at the election being stolen which everyone doesn't know is flat-out lies."

The possible protests come just over 10 days since the Capitol was breached on Jan. 6.

In Harrisburg, Pennsylvania, Stephen Rzonca, who lives a few minutes from the state Capitol, said he came to greet any possible demonstrators, although there were none as of mid-day.
"I'm fundamentally against the potential protesters coming here to de-legitimize the election, and I don't want to be passive in expressing my disapproval of them coming into this city," Rzonca said.
And before demonstrators arrived in Lansing, Michigan, a truck showed up with a sign supporting Democratic Gov. Gretchen Whitmer, who was the target of a foiled kidnapping plot last year.
At the U.S. Capitol, as federal officers, District of Columbia police and National Guard troops patrolled the area, a lone protester walked the sidewalk wearing a sign that said "Renounce Trump!"
More than a week after the attack on the U.S. Capitol, federal authorities continue to charge people who allegedly participated in the riot, often relying on video taken at the scene to identify suspects.
As of Saturday, approximately 80 cases have been charged in federal court and at least 40 people have been arrested in connection with the attack, the Department of Justice said. Additionally, the FBI has opened approximately 200 subject case files and received roughly 140,000 digital media tips from the public.
