On Dec. 20, a Black Lives Matter protest drew as many as 3,000 people to the Mall of America rotunda. Twenty-five protesters were arrested, and the city of Bloomington, Minnesota, also filed charges against 11 alleged organizers for offenses such as unlawful assembly, trespassing, disorderly conduct, and public nuisance. The city of Bloomington is still seeking $25,000 in restitution (to cover police overtime) from the 11 people charged.
