This past week, hundreds of people took to the streets to express outrage at a judge’s decision to find former St. Louis police officer Jason Stockley not guilty of first-degree murder in the 2011 death of Anthony Lamar Smith. The protests largely have been peaceful. But police have made numerous arrests since the demonstrations began. On Sunday alone, police made 123 arrests — largely on a charge of failure to disperse. They also charged a few people with the destruction of property or assault.
