DENVER — An estimated 50 people gathered to protest in downtown Denver Wednesday night. They’re voicing their disagreement with a grand jury’s decision not to indict the police officer who killed Michael Brown in Ferguson, Missouri.

The group marched around downtown for about three hours before ending their activities just before 9 p.m.

Police officers kept an eye on the protest but it took place without any confrontation.

There were a couple of arrests.

Organizers did not know if they would be back for more protests during the holiday weekend.
