Protesters took to the streets of downtown Charlotte, North Carolina, on Wednesday night to show their disappointment with the decision to not charge an officer in the shooting death of Keith Lamont Scott.

A two-month investigation determined that Charlotte-Mecklenburg police Officer Brentley Vinson was justified in shooting  Scott in an apartment complex parking lot. Mecklenburg County District Attorney Andrew Murray said he didn’t reach the conclusions alone; a total of 15 prosecutors unanimously agreed with the decision.

The killing led to heated protests and divided the city of Charlotte. Compared to previous demonstrations over Scott’s death, a smaller crowd turned out Wednesday night, about 100 people. At least four people were arrested as police tried to corral protesters off the streets, three for obstructing traffic.
