Wednesday, a federal judge placed restrictions on the St. Louis Metropolitan Police Department, claiming their conduct during recent protests has violated demonstrators’ constitutional rights.

U.S. District Judge Catherine Perry ruled that the plaintiffs in a lawsuit against St. Louis police “are likely to prevail on the merits of their claims” that their First and Fourth Amendment rights had been violated.

The case stems from protests which took place in September, following the “not guilty” verdict in the murder trial of Jason Stockley, a white police officer who shot and killed Anthony Lamar Smith, a black man, in 2011.

Perry found sufficient evidence that although there was no violence, police declared an assembly without taking the protesters' rights and opinions into consideration. She also ruled that there was “no credible threat of force or violence to officers or property” when police rounded up citizens, including journalists, on Sept. 17. Following those arrests, the sitting head of the St. Louis MPD declared his department “owned” the night, as the officers mocked protesters by chanting "Whose streets? Our streets!"

Perry shared that officers had clearly retaliated against protected First Amendment speech simply because they did not prefer being criticized, and used chemical weapons to divert speech they didn’t favor. 

“Plaintiffs’ evidence — both video and testimony ― shows that officers have exercised their discretion in an arbitrary and retaliatory fashion to punish protesters for voicing criticism of police or recording police conduct,” Perry wrote. “When all of the evidence is considered, plaintiffs have met their burden of showing that they are likely to succeed on their claim that defendant has a custom or policy of deploying hand-held pepper spray against citizens engaged in recording police or in expressive activity critical of police in retaliation for the exercise of their first amendment rights, in violation of the First, Fourth, and Fourteenth Amendments.”

Perry says police are not permitted to declare an unlawful assembly unless there’s a clear and present threat, and they cannot use the law to punish people engaged in protected activity, such as protesting. Perry additionally confirmed chemical agents can’t be used, unless there is probable cause to arrest, and police are not able to threaten to use chemical agents against anyone engaged in expressive, nonviolent activity. 

In October, during a hearing, American Civil Liberties Union attorney Anthony Rothert proclaimed “pepper spray is the new fire hose,” and said officers were using pepper spray “arbitrarily, gratuitously and without warning.” We are hopeful that more injustices will be brought to light and rightfully punished, as well as justice be served as these officers and others misusing their duty to serve and protect are corrected.
