Six businesses and at least one car were set ablaze as violence erupted Saturday night following an officer-involved shooting that left a 23-year-old man dead. Four police officers were injured, including a female officer who was hit by concrete and suffered a concussion, Milwaukee Police Chief Ed Flynn said Sunday. They have all been released from area hospitals. Seven squad cars were damaged, and two bus stop shelters were thrown into the street. By late Saturday night, fires were reported at a BP gas station, a Jet Beauty Supply store, an O'Reilly Auto Parts store and a BMO Harris Bank location. Several blocks away, a neighborhood supermarket was on fire at about 1 a.m. Sunday. A liquor store at 22nd Street and Fond du Lac Avenue was burning shortly after 2 a.m. Seventeen people were arrested overnight, Flynn said on Sunday. Barrett warned parents to ask their children to come home if they are out on the streets protesting. "If you love your son, if you love your daughter, text them, call them, pull them by ear and get them home," Barrett said.

He also said he wants to see the body cam video from the officer involved in the shooting as soon as possible. Flynn said the video shows a brief chase, the suspect being confronted by the officer and the that the suspect had a gun in his hand. He said there is no evidence the suspect fired a shot. "We didn't accomplish anything with destroying, you know, property. You know, however, I think that the conditions in this neighborhood throughout the summer have been festering, you know?" Milwaukee Alderman Khalif Rainey said. "It's not just about the incident that occurred yesterday, it's about all the incidents that occurred prior to this and a lot of city officials with laissez-faire, sitting back, you know not really, having a response. I hope if anything, this has demonstrated this community has a great need. We have a great need over here and there needs to be investment. There needs to be support. There needs to be resources that's attributed to this neighborhood. " Police said a social media call for protesters after the shooting led to some 800 people at its peak. The violence near North Sherman Boulevard and West Burleigh Street exploded after a 23-year-old man was shot and killed by an officer following an afternoon traffic stop about a block away, on the 3200 block of North 44th Street, Capt. Mark Stanmeyer said. Two people bolted from the car during that traffic stop, Stanmeyer said. An officer, a 24-year-old man with six years of service with the department, shot the man during a foot chase. He died at the scene, and Stanmeyer said the semiautomatic handgun with which the man was armed was taken in a burglary in Waukesha in March of this year. The victim of that burglary reported that 500 rounds of ammunition were stolen with the handgun. The man who was killed had a "lengthy arrest record," Stanmeyer said, though he did not offer details. The other person who police say ran from the car, another 23-year-old man, was taken into custody. "That officer had to make a split-second decision when the person confronted him with a handgun," Milwaukee Police Assistant Chief Bill Jessup said. "This is a risk they take every day on behalf of our community." Flynn said Sunday that the officer who shot Smith is African-American. "We're concerned for his safety," Flynn said. More than 100 people gathered after the shooting, some helping to quell the rising tension, as several dozen yelled at police officers. Additional officers, some of whom donned riot gear, were called in.The District 7 officer was not injured. He will be placed on administrative duty during the investigation and subsequent review by the Milwaukee County District Attorney's Office. Milwaukee County District Attorney John Chisholm said he has two roles: making sure the investigation into the officer-involved shooting is handled independently by the state Department of Justice and to oversee any charges that may come from the night of violence. "Any other efforts that we can use to calm the situation and make sure that the people responsible for any criminal acts tonight are held accountable -- we're going to do that as well," he said. Sunday Sunday morning, cleanup was underway on the north side after a night of fire and violence. "Help be part of the solution, help with the cleanup and show everybody we are together," said Mary Carmen, who was cleaning up. "We need to unite and turn this negative image we have of Milwaukee and show the country and show the world how we are one." A couple of small trash fires were spotted by News Chopper 12 but put out quickly. Nate Hamilton, with the Coalition for Justice, said he wants change to happen within the community without any violence. The group wants to clean up and rebuild the city. "As details of this officer-involved shooting emerge, I ask our community to remain calm. Together, we will weather this storm," U.S. Rep. Gwen Moore tweeted. A youth minister,visiting from Ferguson, Missouri, told WISN 12 News' Kent Wainscott that the unrest in Milwaukee is a "mirror image" of what happened in Ferguson.
