Protests erupt in St. Louis after ex-officer’s acquittal

Protesters chanting “free our people” gathered outside the jail in downtown St. Louis for more than two hours to show solidarity with those arrested during demonstrations that turned ugly over the weekend, but there was no new vandalism overnight.

Demonstrators outside the jail late Monday criticized authorities for keeping some of those arrested in jail for nearly 24 hours after they were taken into custody. Police said more than 120 people were arrested during Sunday’s protests over the acquittal of a white former police officer in the killing of a black suspect.

Some of those jailed were released Monday evening before organizers announced an end to the demonstration and told people to go home. Organizers said protests will resume Tuesday, but they gave no details.

Monday was the fourth day of protests.

Three days of peaceful protests and three nights of vandalism followed Friday’s announcement that a judge found ex-officer Jason Stockley not guilty in the 2011 death of Anthony Lamar Smith. (AP)
