CLAYTON, MO (KTVI) - Protestors gathered outside the St. Louis County Police Headquarters in Clayton Wednesday afternoon. Demonstrators said they came to express their democratic voice on the, "National Day Against Police Brutality." They planned to speak at a scheduled public meeting of the St. Louis County Police Commission, but it was abruptly cancelled.

Brown, 18, was shot and killed by a Ferguson Police officer in August. Demonstrations have now gone on for more than 70 days. New details have emerged recently about the shooting. Leaks have appeared in the St. Louis Post-Dispatch and the New York Times from the officer involved in the shooting that sparked the protests.
