VIDEO: Dozens of Protesters Arrested Outside of IACP Show in Chicago

A total of 66 people were arrested as they demonstrated outside McCormick Place while a group of police chiefs from across the country met for a conference inside Saturday. 

Nineteen adult men and 47 adult women were arrested on misdemeanor charges of obstruction of traffic by a non-motorist, according to Chicago Police News Affairs.

The crowd of demonstrators first gathered outside police headquarters at 35th and Michigan Avenue, and then they marched up King Drive toward McCormick Place, where police chiefs from across the country gathered for a conference with the International Association of Chiefs of Police.

The protesters came from several different organizations, but they were all involved in the "Black Lives Matter" movement, NBC Chicago reports.
