She was arrested and charged with crowding, obstructing or incommoding after she crossed police lines, according to ET. She was reportedly fined $50 and processed on the scene.
And while the Daredevil star, 36, told reporters after her release that "the police were really great with us and really lovely, I have to say that is not the case for so many people," including Black Lives Matter activists and others.

Dawson – wearing a jacket bearing a likeness of presidential candidate Sen. Bernie Sanders – joined others this week demonstrating at the Capitol as part of Democracy Spring. Their protests, including a march and mass sit-ins, seek to draw attention to what they call the corrosive effect of "big money" in politics, among other issues.
"We're putting ourselves on the line for what a lot of people across America, and I think across the planet, really, want to be able to see happen in America," Dawson said afterward.
She said police on the scene, "in general," were "really kind and very sweet with everyone," she told reporters. And while she said she was warned multiple times that she would be arrested, it appeared as though police were reluctant to do so because of her high-profile.
Dawson said her commitment to join the actions of the larger group was about highlighting that perceived double-standard, about her treatment versus others – and "for me personally, to be in solidarity with the other folks who put themselves on the line."
U.S. Capitol Police and Dawson's reps did not immediately respond to PEOPLE's request for comment.
But in a Friday news release obtained by PEOPLE, the Captiol police confirmed the arrests of about 130 people on the Capitol plaza, for crowding, obstructing or incommoding, after which those arrested were processed and released on the scene.
