The states also reinforced their defenses by setting up fences and barriers, closing boarded windows and calling on the National Guard.
So far, major security efforts have outpaced protests that have materialized. But tensions remain high.
On Sunday, small gatherings of protesters, some of whom were armed, stayed outside the capitals in Michigan, Ohio, Texas and several other states, but many other state capitals that prepared for the worst found only a handful of people. All the protests were peaceful.
Security efforts have extended to the verification of members of the National Guard arriving in Washington for possession in the case of an “internal threat”.
Almost silent protests so far
FBI Director Christopher Wray warned last week that the FBI has seen “extensive” conversations around the inauguration.
“Together with our partners, we evaluate these threats and what kind of resources to use against them. We are currently monitoring calls for possible armed protests, ”he said.
Since then, there have been some armed demonstrators in the state capitals, but the ones that took place were relatively small and with different political views.
The heavy security and continued arrests of people who participated in the attack on the United States Capitol may be playing a role in discouraging protests.
Anti-government groups that promised to show up days before the inauguration appear to have been frightened in part by their own conspiracies that the government was behind some of the national protests that have so far failed.
Law enforcement officials say there is an extensive surveillance network focused on people in the groups who participated in the attack on the Capitol. One of the prominent emerging themes is that the anti-government conspiracies that propel groups such as the Oath Keepers and other militants have become a motivator to avoid the protests, fearing that they are being sentenced to prison.
Some of the people most likely to attend these types of events are also trying to lower their profile after participating in the insurrection, police officials said.
Some saw their faces on FBI posters that circulated last week. In some cases, members of the groups surrendered, hoping to gain some benefit from not waiting for the FBI to find them.
