Scott's family has said he was not armed and was holding a book while waiting for his son to be dropped off from school.
Police said Scott, 43, was not the suspect officers sought.
Officers in riot gear gave multiple orders for the people to disperse, and when they didn't, police deployed tear gas.
"We join the people in Charlotte and across the nation in sending our deepest condolences to Mr.
Scott's family," said Karen Anderson, the executive director of the North Carolina ACLU.
