Beginning on the afternoon of September 15, 2017, a series of protests took place in St. Louis, Missouri, following the acquittal of former St. Louis police officer Jason Stockley in the shooting of Anthony Lamar Smith, a black man. Over 160 people were arrested during the first three days of demonstrations, with largely peaceful protests. There has been significant criticism around the police and governmental response to protests, resulting in lawsuits from the ACLU.

Timeline of events

September 15

Roughly 200-300 demonstrators assembled in downtown St. Louis near the city courthouse. The protests were mostly peaceful. Police used pepper spray to drive back protesters on at least two occasions: after protesters responded angrily to the approach of buses filled with police in tactical armor (riot gear), and after individuals mounted an abandoned police vehicle and damaged its windshield.

Demonstrations later moved to the Central West End neighborhood, where they swelled to over 1,000 people. They were peaceful until about 9:45 pm, after protesters made their way to the home of mayor Lyda Krewson. Despite urgings from demonstration leaders, at least one protester put a rock through the mayor's window. The mayor is believed not to have been home. Although most demonstrators dispersed immediately, police deployed pepper spray and tear gas, driving back remaining demonstrators and onlookers through the Central West End's commercial area. There, angered protesters damaged several businesses.

A group of protesters attending a baseball game between the St. Louis Cardinals and the Milwaukee Brewers at Busch Stadium unfurled a banner which depicted a cardinal, to match St. Louis' baseball mascot, with #ExpectUs written across the bird's jersey and the bird holding a "Black Lives Matter" sign, and read at the bottom "Stop Killing Us." The protesters were removed from the stadium by police. At least two protesters were arrested as ongoing demonstrations outside Busch Stadium continued as well.
