"This is a tremendous issue and I'm grateful that I could be here and be a part of it. I wanted for me, personally, to be in solidarity with the people who put themselves on the line," Dawson told reporters in a YouTube clip that has since circulated on the Internet.
She was apprehended for "crowding, obstructing, or incommoding" after she crossed police lines during the rally. She was fined for USD 50 and processed on site.
