The Rev. Jesse Jackson called the shooting a tragedy and said in a statement that it's a blessing Augustus didn't bring the girl with him Saturday, as he's known to do.
Though police have yet to release the victim's name, activist organization Black Youth Project 100 identified him on Twitter as local barber Harith "Snoop" Augustus.
Augustus had been armed with a "semiautomatic weapon" and "had magazines on him", Waller said Saturday.
The man was shot multiple times and then drove himself to a gas station several blocks away at 7001 S. Stony Island Avenue, where someone called an ambulance, police said.
As officers tried to contain the crowd, some of them dragged people to the ground or struck them with batons.
"From police perspective, you know, these things happen in a split second", Chicago Police Superintendent Eddie Johnson said during a press conference Sunday.
The man became combative and eventually broke free from the officers, Chief Waller said. Some threw rocks and bottles at police. An officer points to Augustus' waist and he backs away.
The man police shot and killed in the United States over the weekend appeared to reach for a gun in his waistband in body camera footage released by authorities yesterday.
Police spokesman Anthony Guglielmi tweeted that four protesters were arrested.
Chicago police released two versions of the same video. A struggle followed and the man was fatally shot.
Chief Waller said protesters threw bottles and jumped on top of a squad auto, with social media videos showing punches thrown on both sides.
The report said that the police department violated the constitutional rights of residents for years, permitting racial bias against blacks and killing people who did not pose a threat.
He said Augustus' family was in favor of releasing the video for the same reason.
Chicago's Civilian Office of Police Accountability say the shooting was captured by body cameras and the circumstances surrounding the shooting are under investigation.
An officer was involved in a confrontation with an armed suspect in Chicago.
In 2015, protesters blocked Interstate 94 after police released a graphic dash-cam video showing an officer shooting 17-year-old Laquan McDonald. McDonald's death led to the departure of the police chief and reforms meant to prevent future police abuses and to hold officers accountable.
