Arrests were almost exclusively for charges of failure to obey a lawful order, Denver police said, but some included interference with police authority, unlawful throwing of projectiles, and obstruction of streets.

The rallies this week sparked by immigration crackdowns in Los Angeles has renewed questions about whether Denver police have learned from past use-of-force violations.

Three dozen protesters were arrested Saturday night in Denver on investigation of charges ranging from blocking streets to resisting arrest, according to the police department.
