More to come

The extremist, pro-Trump, ecosystem online is calling for an armed rally this Sunday with more to follow.

Washington Mayor Muriel Bowser as well as federal law enforcement say they are looking at potential security threats, and large gatherings are expected to be banned. In addition, Biden's inauguration will have almost no crowds due to COVID.

However, Jen Golbeck, a professor at the University of Maryland who follows extremists online, said she is most worried about an individual or a small group seeking to cause trouble.

"It's easier to protect against a big group than a few individuals who are really committed to doing violence and who can't be deterred," she said. "That is language that I'm seeing a lot of online, not from thousands of people, but from dozens of them."

She said the inauguration and landmark buildings in Washington will be well protected, and therefore many not be targeted. But plenty of other places have drawn the ire of the far right and need to have strong security in place, she added.

Last week, some of those taking part in the Trump event posted online maps that provided the locations of many leading media organizations in Washington.

And outside Washington, she added, targets could include state capitols. With some tech companies suspending Trump's social media accounts and those of his supporters, Silicon Valley could become a target. Golbeck even worries about Amazon delivery drivers, since the company's web services stopped hosting Parler, the social media site that attracts many on the far-right.
