There were also reports from demonstrators of aggressive responses from police, including the macing and violent takedowns of compliant demonstrators.
Police made more than 80 arrests, after authorities said people ignored orders to disperse following the peaceful protests. Demonstrators countered that police boxed them in, giving them no way to disperse. At least one credentialed reporter and several members of the public who were live-streaming the protests were detained.
Mayor Lyda Krewson told reporters early on Monday: “The days have been calm and the nights have been destructive.” Krewson said that was “unacceptable” and that “destruction cannot be tolerated”.
City police described being attacked by protesters using “unknown chemicals”. Demonstrators countered that the liquid some carried in bottles was apple cider vinegar, which some use to counter the affects of teargas. In one picture posted to social media by police and described as an effort to “confiscate bottles with unknown chemicals”, one bottle was clearly labelled “apple cider vinegar”.
One officer suffered a leg injury and was taken to a hospital. His condition was not known.
On Monday, daylight brought calm. A racially mixed crowd of more than 150 blocked a busy street on the western edge of downtown, while state representative Bruce Franks was at the front of a march to city hall. Protesters chanted: “We will win together” and demanded a civilian police review board, then disbanded.
A judge ruled on Friday that Stockley, a 36-year-old who left the St Louis department and moved to Houston three years ago, was not guilty of murder in the death of Smith in 2011. Smith fled from Stockley and his partner as they tried to arrest him for a suspected drug deal. Stockley testified he felt endangered after he saw Smith holding a silver revolver when he backed his car toward the officers and sped away.
Prosecutors said Stockley planted a gun in Smith’s car. The officer’s DNA was on the weapon but Smith’s wasn’t. Dashcam video from Stockley’s cruiser recorded him saying he was “going to kill this motherfucker”. He shot Smith five times.
Stockley’s lawyer dismissed the comment as “human emotions” during a dangerous pursuit. St Louis circuit judge Timothy Wilson said the statement could be ambiguous.
Protests over Stockley’s acquittal have followed a pattern born of the reaction to the killing of Michael Brown, an unarmed teenager, in nearby Ferguson in 2014. The majority of demonstrators are law-abiding. As the night wears on a subsection emerges, more willing to confront police.
Many protesters believe police provoked demonstrators by showing up in riot gear and armored vehicles. Police said they had no choice but to protect themselves.
Democratic representative Michael Butler said police should target the agitators and allow others to continue demonstrating.
“There’s not been any learning from Ferguson,” he said.
